From DDOT: The District Department of Transportation (DDOT) advises motorists that the exit ramps from South Capitol Street to both I-395 northbound and southbound will be closed for maintenance from Monday December 4 through Thursday December 7 from 8 pm to 4 am. The below detour will be set-up to guide motorists:

The planned 1.1-million-sq-ft Florida Rock development at 1st and Potomac Avenues (across the street from the new Nationals ballpark) had another Zoning Commission hearing last night, to address some of the concerns expressed by the ZC at the first hearing in September, chief among them the design of the east end of the east office building (see map to orient yourself), which commissioners felt disrupted the line of sight to the Anacostia River from the stadium's grand staircase and viewing platforms. This section of the building--which will house a signficant portion of the project's retail offerings--has now been redesigned so that one will be able to see the Earth Conservation Corps pumphouse from the center of the staircase. This eastern end of the development also faces the new planned First Street Plaza, a 40,000-sq-ft public park to be placed at the terminus of First Street, to draw people to the riverfront. Florida Rock is proffering $3.7 million toward the design, construction and maintenance of this park that the Anacostia Waterfront Corporation will develop (total cost estimated to be $15 million). The record is being held open for two more weeks, so look for a vote on the project at the January 8 meeting; I hope to have updated renderings showing the redesigned east building by that point. As for a timeline, Florida Rock estimates that construction on the first phase--the east office building--would begin in early 2008; there has been no announcement from the AWC as to any sort of timeline on the First Street Plaza (which presumably also depends on the acquiring of the WASA land on that site).
