If you are looking for some light Christmas reading, you can sit down by the fireplace with all 335 pages
(plus appendices!) of the newest revision to the plans for reconfiguring much of South Capitol Street
, including the construction of a new Frederick Douglass Bridge
The bullet points for what the project plans are north/west of the Anacostia River are in the graphic at right (click to enlarge
). The changes in this new RPA include:
* Changing the design of the bridge from a moveable span to a fixed-span bridge, which would save approximately $140 million in construction costs;
* Shifting the orientation of the new Douglass Bridge to an alignment parallel to the existing bridge, 30 feet down river, which avoids the need and lengthy process to acquire some land from Joint Base Anacostia-Bolling as well as a number of expensive relocation and reconstruction issues that a new alignment avoids (see page 2-91 of the SDEIS
* A slight reduction of the size of the traffic oval on the western side (at Potomac Avenue):
* Replacing the previously designed circle on the eastern approach with an oval, located entirely in the DDOT right-of-way;
* And several other changes on the east side of the project that I will leave to others to discuss in detail. (See page ES-6 of the SDEIS
The initial design of the ovals and of the bridge itself were met with some consternation
during this revision process. The SDEIS notes that in response to these concerns, DDOT has created a "Visual Quality Manual" for the project, which identifies design goals that are to "reflect the vision of providing a grand urban boulevard, which will be a gateway into the nation's capital, an iconic symbol of the District's aspirations in the 21st century, and a catalyst to revitalize local neighborhoods and the Anacostia Waterfront." (page 2-26).
As for the bridge itself, the version in this RPA will support three travel lanes in each direction, along with 18 feet of bicycle and pedestrian paths on *both* sides of the bridge--an 8-foot lane for pedestrians and a 10-foot birdirectional bike path. (Enlarge the image at right
to see that I'm not lying about the bike/ped stuff.)
And the design of the bridge is to "make its primary aesthetic impact through its position (alignment), and the shape and sizes of its structural elements" and is to " aesthetically appear to be part of a continuous urban corridor." This includes the avoidance of "using elements, solely for aesthetic effect, which do not contribute to the support of the bridge." (page 2-28)
Plans for the reconfiguration of South Capitol Street
as a "grand urban boulevard" have all along called for changing the intersection of South Capitol and M streets to an "at-grade intersection
" (page 4-79), which would also mean that K and L would have signalized four-way intersections with South Capitol, unlike today. The wide median seen south of N would be established on the north end of the street as well, now all the way to D Street SE in the RPA. Also changing in this new plan are a few new left-turn options at I Street SE/SW and L Street SE.
Revisions have also been made to the ramps from South Capitol Street to I-395 and I-695, but the basics from the original plans remain, most notably the demolition of the existing suspended ramp from northbound South Capitol to the SE/SW Freeway.
Even with the revisions made to cut the costs of the new Douglass Bridge, this isn't a cheap project. The five phases
together are anticipated to cost over $1 billion, with Segment 1, including the new bridge and traffic ovals, estimated at $480 million. The "grand boulevard"-izing of South Capitol Street is estimated at $153 million, and planned streetscape improvements to New Jersey Avenue between D and M streets SE at $42 million, plus another $358 million in east-of-the-river improvements (page 2-11).
Worn out yet? I sure am! (I've mostly lost track of how much of this is truly even "new" news at this point.) But perhaps you can regain your strength by Jan. 22, 2015, when the public meeting on this SDEIS will be held from 6:30 to 8:30 pm at Matthews Memorial Baptist Church Fellowship Hall
, 2616 Martin Luther King Ave., SE. The public comment period is running until Feb. 2. DDOT is also still amidst the design/build proposal process
, with proposals expected sometime in the spring.
