Over the next few weeks, weather permitting, workers will be demolishing bridge spans that runs above N Street, SE (that little connector road between 12th Street and the Navy Yard gate on 11th). This is part of the 11th Street Bridges
project, and is the continuation of the demolition of the no-longer-needed ramps to and from RFK. (Note that the spans that still carry 11th Street Bridge traffic aren't coming down!) Here's the specifics on time-frames and lane closures:
""Sunday through Thursday from June 6 through July 1, weather permitting, contractors for the District of Columbia Department of Transportation (DDOT) will perform bridge demolition work above N Street SE requiring overnight closures of the street between the 12th Street SE and the gate of the Navy Yard on 11th Street SE. The closures will occur each night from 8 p.m. to 5 a.m. the next morning with a signed detour provided.
"Also during this timeframe, the following lane closures will be instituted for related bridge demolition activities:
"* The left lane will be closed on the ramp from Southeast/Southwest Freeway to I-295 South/Martin Luther King Jr. Avenue continuing across the outbound 11th Street bridge and ending prior to merge area with I-295.
"* The left lane will be closed across the inbound 11th Street bridge beginning on I-295 north near Howard Road and ending past the M Street/12th Street exit ramp.
"All of these closures may be subject to change due to weather or other unforeseen conditions."
Here's a zoom in
on the Google Maps satellite view if you need some visualization assistance. It's the first and third (from the left) of the four "spans" above N Street are the ones that go to and from RFK. I also wonder if this means that the big embankment that runs along 11th Street
between M and N is coming down--I would think so, since it's now an unused stub.
