presentation on Washington, D.C.'s Southeast/Southwest Freeway
Good insofar of its inclusion of a Washington Channel Tunnel as proposed in 2008 by U.S. National Capital Planning Commission
Poor insofar of its zero discussion of construction feasibility, of tying the Washington Channel Tunnel into the existing freeway trench and in removing the elevated segment to the east with a lowered replacement.
Impractical in its renderings showing the row of Capitol Square Townhouses closest to the southern retaining wall of the SW Freeway between 10th and 7th Streets SW., as staging the freeway tunnel reconstruction project while maintaining traffic, would require a new excavation along the southern side.
Impractical in removing the freeway to the east of the Center Leg without a replacement tunnel, particularly given the recent 11th Street Bridges reconstruction which added new high capacity ramps to the south of the Anacostia River to and from the northeast with DC295.
