New phase on 14th St. bridge

Drivers entering the District on Interstate 395 this weekend should watch for a developing change in the traffic pattern on the northbound 14th Street bridge and the closing of the ramp from northbound I-395 to the 12th Street tunnel. Also, D Street SW, just east of 12th Street, is closed.

14th Street bridge
Throughout the weekend, workers are finishing up the phase of the bridge rehabilitation project that blocked part of the second lane from the right on the northbound span. They're shifting traffic in preparation for Phase 3, which will block part of the third lane from the right.

The concrete barriers now blocking the second lane from the right will be moved one lane to the left. This shift is scheduled to occur before 5 a.m. Monday, but for a while this weekend, drivers could find the two middle lanes blocked.

By Monday morning, if work goes as planned, commuters will find four lanes open, but the configuration will look different as they approach the bridge. They will be able to get by the new work zone on either side. But if they're heading for 14th Street downtown, they should stay in the left lanes.

12th Street tunnel ramp
Meanwhile this weekend, the District Department of Transportation has closed the ramp from northbound I-395 to the 12th Street tunnel, and nearby D Street SW is closed till 4 a.m. Monday. Workers are installing pavement markings and guard rails, and making other fixes that are part of the rehabilitation project on the 11th Street SW bridge (not to be confused with the 11th Street Bridge over the Anacostia River).

Detour:
Drivers coming across the 14th Street bridge from Virginia this weekend will need to take an alternate route. They can go north on 14th Street to get downtown. (Remember to stay to the left on the 14th Street bridge.) Or they can take the L'Enfant Plaza exit to D Street SW. Detour signs will direct drivers to Seventh Street.
