21st Century Washington, D.C. Freeway System

The government wants to spend trillions on COVID relief and upon infrastructure.  But will they dare ever do anything about the inadequate and incomplete Washington D.C. freeway system?

Builds upon and corrects deficiencies of past planning.

Corrects capacity and geometric restrictions at the northern Capital Beltway Rock Creek Park passage, with Capital Beltway entirely buried from Wisconsin Avenue to Seminary Road in box tunnel beneath an expanded Rock Creek Park.

Designs a Central Artery - B&O Route North Central Freeway - faithful to the 1962 JFK Administration endorsed concept that the feds undermined following 1963.  It would be fed from the northwest with its own carriageway connections to I-270 via the above reconstructed Beltway segment.  And it would be fed from the northeast via a tunnel alongside New Hampshire Avenue for the PEPCO power line corridor I-95, further refined as a cut and cover tunnelway design for an expanded RR and a new bottleneck free highway beneath a new linear park- what would be Washington, D.C.'s new North Mall/Grand Arc.

Reconstructs the SWSE Freeway from just west of Washington Channel to at least 3rd Street SE as an expanded cut and cover tunnel, with added capacity to eliminate the northeast to southwest traffic flow bottleneck for the Center Leg-SW Freeway combo.  Augments the Center Leg with parallel tunnels under 2nd and 3rd Street, with tunnel extension to the northeast under O Street for a single block west and east of North Capital Street.  Restores the recently decommissioned east of 11th Street SE Freeway as box tunnel covered facility, under a new surface boulevard, and extends this past Barney Circle, under a new pedestrian waterfront promenade to RFK Stadium/East Capital Street, with box tunnel continuing to the northwest to connect with the North Mall/Grand Arc Central Artery to I-270 and I-95.  The design would include a set of tunnel links crossing each other descending to pass under the Anacostia River, initially of a north-south I-295East Leg tunnel, and subsequently - as part of what could be a subsequent project to reconstruct the 11th Street Bridge approaches underground - an easterly SE Freeway link to a DC295 corridor reconstructed in cut and cover tunnel, with separate carriageways for north-south I-295, and east-west traffic, promoted by a new cross Potomac Tunnel to Virginia 110, optionally designated as I-66.

Design a NW system of radials and intercepting downtown system: westerly; an I-266 starting in Virginia via a 3 Sisters Tunnel, and west-northwesterly via a Canal Road Tunnel with a completed Clara Barton Parkway, merging together entirely within tunnel under the Georgetown waterfront, with West Leg connections to and from the south, and then K Street with a parallel tunnel under N Street-Rhode Island Avenue-O Street, to connect with the Central Artery; a north-northwesterly drilled NW Freeway tunnel emanating from the Wisconsin Avenue corridor into a reconstructed West Leg that splits to its south to: 1) a cross Potomac Tunnel to Virginia Route 27; and 2) a connection to a reconstructed, more capacious, underground SWSE Freeway.

New Development Threat To New York Avenue Area I-395/new I-195 Extension

New public right of way threat: "Douglas Development" 557 unit residential building, architects HOK Architects, to be built upon now empty triangle between O Street and the heavily used North Capitol Street and New York Avenue.

Take a close look- 
way more building displacement along the west side of North Capitol Street?


O Street is by far the best alignment for a tunneled extension of I-195 (I-395 is being re-named) to the northeast, presenting the best geometry (the curved transition has a greater turning radii of any of the alternate plans, even those from the 1950s, let alone the horrifically deficient 1996 "Ron Linton" plan) with comparably little displacement.

The O Street Tunnel would use the entire right of way with, as defined by the northern edge of the recently built Dunbar High School building, removing the buildings to the east along the southern side of that street for one (1) block, with that right of way continuing due east of North Capitol Street through the now empty lands to the vicinity of the Wendy's ("Dave Thomas Circle"), before turning to follow the northern side of New York Avenue to the confluence of the two main railroad corridors.

Where is new U.S. Transportation Secretary Pete Buttigieg on this?  

Does he support an O Street I-195/I-395 tunnel to fix that area so it can be better developed than it would otherwise be as an open traffic sewer?  Does he support of a truly comprehensive transportation plan that gets our Capital City highway system back on track with a modern primarily underground express system, with its centerpiece of a multi-model, linear park covered North Mall/Grand Arc project establishing needed highway links, along with improved rail service, all designed to fit together.

Or does he support Washington DC's traditional economic/environmental racism of "de-emphasizing" the 3rd Street Tunnel/Center Leg (see my numerous posts on this blog regarding DEVELOPER THREATS TO OUR RIGHT OF WAYS), with the longstanding local Washington D.C. racist polices of pushing the traffic burden disproportionately upon the area's least affluent areas in SE?

Letter From Georgetown Law On The Center Leg Cover & Chock Project

As usual, no mention of the crime.

 Wallace Mlyniec

April 10, 2013

Dear colleagues,

You may have noticed some activity on the road bed and on the streets surrounding the I 395 freeway west of the Law Center. If so you would have seen engineers drilling core samples to test the composition of the soil and to search for archeological remnants in the area. A construction company, Balfour Beatty, has also converted the pink building at the corner of 3rd Street and Massachusetts Avenue into a construction management center. These activities signal the early stages of the development project over the highway.  The development was formerly known as the Air Rights Project or the Return to L’Enfant, but is now known as Capitol Crossing.

As you may recall, the developers, Property Group Partners (PGP), intend to build a deck over the freeway between E Street and Massachusetts Avenue. Depending on how one counts, 5 or 6 buildings will be erected on the deck for offices, housing, and retail activities. The retail spaces, which will be located on the first floor of Massachusetts Avenue, 2nd Street, and 3rd Street, will add vibrancy and needed services to our neighborhood. The apartment building will add new residents in about one hundred and fifty rental units. When completed, the project will contain approximately 2.4 million square feet of occupiable space, bringing 24-hour activity to the neighborhood. The buildings, all LEED certified with green roofs, will be 12 stories tall. Unfortunately, this will eliminate our views to the west.
The rectory of Holy Rosary church, which now sits in the middle of F Street at 3rd on the other side of the freeway, will be demolished and rebuilt behind the church. This is where it was sited before the freeway was built. The Jewish historical synagogue, now located on 3rd Street near Massachusetts Avenue, will be moved to the Building Museum grounds during construction and then to a site on the corner of 3rd and F Streets.

The current entrance to and exit from the freeway heading south, now located on 3rd Street, will be eliminated and a new freeway entrance heading south will be created from Massachusetts Avenue. The exit going north on 2nd Street, now reaching street level alongside the Williams Library, will be relocated slightly to the south of where it is now. Our driveway on the 2nd Street side of McDonough Hall will remain once construction is completed.

G Street between 2nd and 3rd Streets will be open only to pedestrians and bicycles. F Street between 2nd and 3rd will be open to automobile traffic but will have traffic calming devices to discourage automobile traffic. Reopening these streets will unite the west and east ends of downtown and give us quicker access the center of the city. Opening F Street between 2nd and 3rd Streets, however, allows the Mayor to terminate our easement for the Tower Green and to reestablish F Street though our campus. Ultimately, this is an issue of contract and politics. We do not expect any conversations between Georgetown and the Mayor concerning this issue to begin for at least three years.

Construction will commence sometime between mid-July and the end of August of this year. The first stage will involve utility replacements under 2nd, 3rd, E, and H Streets and under Massachusetts Avenue. The developers are still studying the civil engineering drawings to determine which utilities need to be replaced. As of today, we are unsure about where utility work will commence, but once started, it will last for 6 months to a year.

The construction of the deck will commence in 2014 after the utility work is substantially completed. Construction will begin at Massachusetts Avenue and move south. If the freeway remains open, it will take 4 years and $250 million to build the deck. If it is closed, the deck can be constructed in 1 ½ to 2 years. The Department of Transportation has not yet issued a decision regarding the freeway closing. Once the deck is completed between Massachusetts Avenue and G Street, construction of the North buildings along Massachusetts Avenue will begin.

Needless to say, our operations will be disrupted. It appears at this time that the most disruptive work will take place during utility replacements on 2nd Street and during reconstruction of the freeway exit onto 2nd Street. Peter Brown and I are working closely with the construction team and thus far, they seem willing to accommodate our needs. They have yet to develop a construction schedule, but we will be working with them to try to have their schedule accommodate the rhythms of our academic year.
We have a team in place at the Law Center to advise Peter and me about Law Center concerns. We have members from the Registrar’s Office, the Department of Security, the Day Care Center, the Gewirz Center, the Facilities Department, the Admissions Office, and the Library. If your work will be substantially impacted by construction and feel the need to be on this working group, please let me know. Once we get closer to the commencement of construction, I intend to send e mails to the Law Center community to keep everyone apprised of the issues.

I have discussed the project with the Associate Deans and the Dean’s senior staff. They will be able to answer many of your questions. Feel free to contact me they are unable to provide an answer.

This project is truly an extraordinary engineering feat. When the project is complete, and that may be ten to twelve years from now, our neighborhood will have a completely different look and feel. Most of the changes will be to the Law Center community’s benefit. I hope you enjoy watching the project evolve.

Why is that ditch there anyway?
by Wallace Mlyniec

A generally good piece, though misleading and erroneous on the cross-town I-66 link
with a few errors- see notes.,d.cGc

Dear colleagues,
As you have undoubtedly noticed, the utility phase of the Capitol Crossing project has begun. Backhoes are digging trenches twenty-feet deep and metal supports are being lowered into the trenches to prevent collapse as workers install and connect sections of a new sewer line to take storm water and waste water away from the neighborhood. I will be reporting more about those lines in another email; but today, as you look at the work going on and the highway behind it, you may be asking yourself, “Why is that ditch there anyway?”

Any modern urban planner looking at the I-395 ditch that bisects the East End of downtown probably recoils in horror and wonders why anyone would deliberately create such a fissure in the urban landscape. Such modern thinking, however, has not always permeated city planning. 

The post-World War II prosperity changed the habits of the vast majority of Americans. Wages rose, home ownership became more common, and suburbia seemed to expand in every direction. Cities became places to work and visit but they were no longer considered the primary place to live. People moved farther from the central cores of cities and their geographic horizons expanded. They discovered new places to explore, places they had only heard of before, and they now had the money to do so. Moreover, the also had the means because the automobile had liberated middle-class America.

Post-War Americans fell in love with the automobile in ways that were different from before the War. Although Henry Ford and his twentieth-century assembly lines made cars easier to make and somewhat affordable, America’s post-World War II prosperity made those cars affordable and accessible to more people. A car of one’s own became every man’s and every woman’s birthright. Coming of age for teenagers meant getting a driver’s license. The cars themselves became works of art, each distinctive in style from those of other manufacturers. Ford, General Motors, and Chrysler created multiple brands and multiple lines within brands. Detroit hummed, producing cars of status like Cadillacs, Mercuries, Packards, and Imperials; but they also made more affordable cars like Ford Fairlanes, Chevys, and Plymouths for middle class Americans. Unlike today’s cars, the cars of the 1950s and 1960s were beautiful and instantly recognizable. You can see some of the classics if you visit
This love affair with the automobile and the desire for fast and convenient travel spawned President Eisenhower’s U.S. Interstate Highway System, considered by many to be the greatest public works project in modern history. As a young officer in 1919, Eisenhower traveled with a convoy of trucks from San Francisco to Washington. The trip took 62 days which gave him plenty of time to notice that there were seldom places to eat, sleep, or repair broken down vehicles along the way. Eisenhower never forgot the rigors of that convoy. His war experiences also impressed upon him the need for good transportation across the land. These experiences, combined with a Cold War defensive mentality, resulted in the passage of the Federal-Aid Highway Act of 1956. The Pennsylvania Turnpike, opened to traffic on October 1, 1940, was then the prototype of the modern, high-speed interstate highway. It, along with the then highly profitable Hutchinson River and Merritt Parkways in New York and Connecticut, were incorporated into the interstate system at the time of its creation in 1956. More freeways and toll roads were soon built or while existing ones were integrated into the Interstate System. Today, the Interstate Highway System comprises 46,876 miles of concrete. For more fascinating information about the Interstate System, visit

America’s love affair with the automobile and the coming of the Interstate Highway System combined to make travel in and out of a city easy; but it also altered the notion of urban planning and ultimately led to the I-395 ditch. Although it is sometimes disputed, most urbanists today would say that planning in the late 1940s and 1950s was focused on transforming the built environment of the country to a suburban form, while at the same time, devising the most efficient way to move cars in, out, and around a city. The District of Columbia was not immune from these influences. Despite the departure of many government employees who supported the war effort, the population of Washington had soared to over 900,000 by 1950. (By the way, today’s D.C. population is only 632,323.) In that same year, the population in the metropolitan area exceeded 1.5 million. Although retailers saw their customers abandoning the inner city for the far edges of the District and for the newly emerging suburbs, the demand for downtown office space accelerated as trade associations, educational societies, and national planning groups recognized that the Federal government intended to retain its primacy in the affairs of the nation and the world. In 1950, there were over 600,000 civilian jobs in Washington, D.C., twice the number there had been in 1940. The police complained that the overwhelming number of cars coming into the city interfered with crime fighting activities. Suburbanites, driving into the city to work, found the city streets congested and difficult to maneuver. Despite their new prosperity and well-being, the suburbanites and the locals were not happy when behind the wheel in the city. 

The National Capital Park and Planning Commission, authorized by Congress in 1945 to rebuild Washington's deteriorated neighborhoods, was beset by lobbyists from many special interest groups, each with a grand plan to end the blight and revitalize the city. Among the more powerful were local transportation officials and the sellers of the beautiful and affordable automobiles. They demanded that transportation within and around the District of Columbia be improved. At first they were extremely successful. In 1947, the Whitehurst Freeway began to move commuters around the congested lower Georgetown area. In 1948, century-old elm trees were destroyed to build the DuPont Circle Underpass that would ease automobile traffic and serve the city's busiest trolley line. The Capital Beltway, originally called the Circumferential Highway, was also designed in the mid-1950s. Its first segment, which included the Woodrow Wilson Bridge, was completed in 1961. The entire 64-mile highway was completed in 1964, at a cost of $190 million. America was moving on wheels and D.C. was not going to be left behind.

The Center Leg Freeway was part of a larger project called the Inner Loop, which itself was part of an even larger scheme to reroute traffic along several corridors through the city and then out to the developing Capital Beltway. The Inner Loop had several segments. The South Leg was designed to run along the Potomac River, connecting a new Southeast Freeway, the 14th Street Bridge, and the new Theodore Roosevelt Bridge, before turning towards Georgetown. There it would connect with the Potomac River Expressway, a new highway that would be paved over the historic C & O Canal. The last part of this plan was eliminated after Supreme Court Justice William O. Douglas challenged highway proponents to walk the entire length of the Canal with him and to discover and then preserve its natural beauty. The East Leg was to have begun at the new Anacostia Freeway, cross the 11th Street Bridge, and proceed along 11th Street near Lincoln Park on Capitol Hill to Florida Avenue. If completed, it would have destroyed a beautiful group of row houses on 11th Street S.E., now called Philadelphia Row, built by Charles Gessford between 1865 and 1867. At Florida Avenue, the loop would turn west and follow along T Street until it turned south above DuPont Circle to join up in lower Georgetown with the Potomac River Expressway. Another proposed highway, called the Northeast Freeway, would have commenced on the East Leg at Florida Avenue, and then continue along the railroad tracks to Silver Spring. Other features proposed at one time or another were an I-66 leg going up K Street from the East Leg to Georgetown, crossing a new bridge over the Potomac River at the Three Sisters Islands, and then proceeding along a new North Leg on 16th Street. [sic*]Planners also proposed an expressway along Missouri Avenue [the Intermediate Beltway, along the route previously proposed for the Fort Drive Parkway] and another, called the Industrial Parkway, that would have run along New York Avenue and then to Baltimore via the new Baltimore Washington Parkway.

  [*sic - This description is potentially confusing.  It is either:

- a vague mention of a later plan that appeared during the mid 1960s for the cross-town I-66 link, within a paragraph that describes the freeway system as planned during the latter 1950s.

The initial plan was for the cross-town I-66 North Leg to run from the west as an open trench freeway continuing from the I-66 West Leg that would be constructed during the early 1960s in the vicinity of today's Kennedy center and the Watergate complex, northerly alongside Florida Avenue and then easterly between U and T Streets to an interchange with the planned northern end of the open trenched Center Leg Freeway alongside New Jersey Avenue.  An eastern extension of the North Leg, continuing upon an elevated berm, would continue to the vicinity of Gallaudet University to meet the northern end of the open trenched East Leg at 11th Street NE.

Opponents to that plan as Elizabeth Rowe by 1965 offered the alternative idea of constructing the cross-town I-66 North Leg via a tunnel beneath K Street, eastward from Georgetown to the Center Leg, and refined by 1971 taking advantage of the geometry by placing the crosstown I-66 tunnel's western approach beneath Pennsylvania Avenue just west of Washington Circle, continuing beneath K Street to the vicinity of Mt Vernon Square and then to its eastern approach tunnel beneath and partially offset to the north of New York Avenue.  The I-66 North Leg would be an essentially east-west route; 16th Street which is a north-south road was never proposed for the east-west North Leg]

- Or, given its linking phrase "crossing a new bridge over the Potomac River at the Three Sisters Islands and then...", the whole sentence should instead read "Other features proposed at one time or another were an I-266 leg from the West Leg along a widened Whitehurst Freeway (which is along the K Street axis in Georgetown) , crossing a new bridge over the Potomac River at the Three Sisters Islands, and then proceeding alongside the Spout Run Parkway in Virginia to connect with I-66.



[*Mlyniec's paper describes the Washington, D.C. freeway system via the plans from the Inner Loop Engineering Study report from 1955, yet shows the system as later vastly re-routed as illustrated from the "Summary of Comparison of Alternative Systems District of Columbia Interstate System 1971 by Deleuw, Cather Associates, Harry Weese & Associates, Ltd."

as proposed in the 1971 
"Summary of Comparison of Alternative Systems District of Columbia Interstate System 1971 by Deleuw, Cather Associates, Harry Weese & Associates, Ltd."

Fearful that the highways would diminish the grand views contemplated by Pierre L'Enfant and George Washington, the planners intended to depress [*sic] the highways below the surface of the city. The Mall would be spared by a tunnel running under the Lincoln Memorial. Each Leg of the Inner Loop would be built below the streetscape and bridged at strategic points. E Street would have a tunnel from 6th to 13th Street, N.W. It would have actually run under the White House. Depressed tunnels were also planned for portions of 9th 12th and 14th Streets. Remnants of this depressed highway system exist today as the E Street Expressway and Virginia Avenue near the Kennedy Center in Foggy Bottom, and at the Center Leg Freeway west of the Law Center. Obviously, such a system would have cut the city into several enclaves isolated from each other by highways, at least until decks could be built over some of them. The old Capitol Hill neighborhood provides an example of how this plan would have degraded the city. The original Capitol Hill neighborhood developed on the banks of the Anacostia River when President John Adams established the Navy Yard. It then grew to the north along 8th Street, S.E. The Eastern Market, a Capitol Hill landmark located today at 7th and C Streets, S.E., was originally sited at about 5th and K Streets, S.E., between the Navy Yard and the emerging Capitol Hill residential neighborhood. Today, the Southeast Freeway, elevated rather than depressed, divides the Capitol Hill neighborhood at Virginia Avenue, hampering efforts to enhance the old 8th Street commercial district and connect the neighborhoods south and north of the highway.

[*sic- its should read "... some of the highways..."  Although the trenched 11th Street East Leg and the Center Leg next to Georgetown Law Center are correctly described, and the author makes the useful observation that these could be eventually decked (covered) over, he only mentions that the Southeast Freeway is elevated rather than depressed, nor that is only so west of 11th Street (the portion to the east sitting on the surface at a sufficiently low where the topography descends towards the Anacostia to permit erecting a deck atop.grade to permit.  He fails to mention that the adjourning segment of the Southwest Freeway is also elevated, and so was the portion of the 1950s design proposal for the North Leg to the east of its connection at New Jersey Avenue with the northern end of the Center Leg.]
The Center Leg Freeway, developed in our East End neighborhood in the 1950s and approved in 1964, was even more devastating to the D.C. urban landscape. By the time the existing portion was completed in 1973, over 400 dwellings were demolished and more than 100 businesses and 1600 residents were displaced. When the Law Center moved to this neighborhood in 1971, the East End was a virtual ghost town. A future email will discuss the devastation of this old, primarily Italian, but integrated neighborhood.

Notwithstanding the approval of the Center Leg Freeway, it was never completed. The portion of the Center Leg that was completed ran a mere 1.4 miles from the Southeast Freeway interchange to Massachusetts Avenue. It was 22 feet below sea level, with a tunnel under the Mall that ran 3,500 feet. Costing $81 million (1972 dollars), it was reputed to be the most expensive highway ever built at the time. It was also the most technically complex. Despite its technological complexity, it became a highway to nowhere.

Most of the Inner Loop plan was scrapped after years of controversy. Lawsuits by the Committee of 100, the D.C. Federation of Civic Associations, and other civic groups, protests by activists like Sammy Abbot and Peter Craig, the demand for a new subway transit system, and the obvious racial discrimination associated with the plan ultimately resulted in its demise. Still, remnants remain. The road along the Potomac River and around the Lincoln Memorial that connects Independence Avenue with the Rock Creek Parkway and the E Street Expressway were built as a compromise. The Theodore Roosevelt Bridge, the Southeast Freeway, the Anacostia Freeway, and the depressed Virginia Avenue in Foggy Bottom are a few parts of the original plan that still exist. Old arguments about parts of the plan resurface from time to time. Debates continue about the existence of an interchange at Barney Circle on Pennsylvania Avenue, S.E., and Virginia legislators still dream of a Three Sister's Bridge. As for the Center Leg, the highway beyond Massachusetts Avenue became a parking lot until 1982 when it was extended to K Street. The extension, however, did nothing to change its fate as a relic from the past. Now that relic will continue its limited purpose but it will disappear from view, buried beneath the new Capitol Crossing project.

The intense and prolonged resistance to the Inner Loop ultimately saved the L'Enfant Plan. Saving it turned out to be critical to the urban renaissance that downtown Washington is experiencing today. For the next eight years, we will be eye witnesses to that renaissance. We will have a close up view as the East End neighborhood is reconnected to the downtown and a part of the original L’Enfant design is reestablished. The ditch will remain but it will be covered by a seven acre deck replete with modern buildings, new residents, and new businesses. I intend to chronicle that journey in the coming years so that you can share in the exuberance of this extraordinary urban project. Stay tuned.

I invite Wallace Mlyniec and his readers to learn about the history and designs of the Washington, D.C. freeway system, as built and as proposed through this blog of mine that I started nearly a decade ago "A Trip Within The Beltway".
