, some closures and road work this weekend that might be of interest:
* "DDOT is scheduled to close the Frederick Douglass Memorial Bridge
(aka South Capitol Street Bridge) for routine testing, from 4 am to approximately 9 am, on Sunday, May 2, 2010. During normal opening and closing operations, the swing span is lowered and then turned or "swung" around in order to allow water traffic to pass. Crews test the swing span each month to ensure it operates properly and make any necessary repairs. The bridge will be reopened to traffic as soon as the test opening and related repairs are completed. In most cases the work is completed ahead of schedule."
* "On Sunday, May 2, from 6 am to 4 pm, contractors for DDOT may stop traffic for five minutes at a time on the 11th Street Bridge, related ramps and portions of the Southeast-Southwest Freeway, to install traffic counting devices in various locations for the 11th Street Bridge Project. The work involves temporarily installing tubing across the traffic lanes and count machines off the adjacent shoulder. Traffic may be briefly stopped with the aid of District Traffic Safety Officers as needed to protect contractors at each location." See the press release
for the list of work zones tied to this.
There's also information on road work for the Case Bridge and the closure of Chain Bridge, but those are outside my jurisdiction!
