On Wednesday, August 12, L Street S.E. will be closed midway between 10th and 11th Streets, S.E., blocking access to 11th St S.E. for the duration of the project. Pedestrian and vehicle traffic and parking will be prohibited on the east end of the 1000 block of L St. This is necessary to accommodate installation of additional pilings, utility relocation work, future excavation work and ultimately construction of the new south tunnel.
As part of the closing, traffic control devices and signs will assist drivers and pedestrians in detouring around the closure. Travelers headed east on L Street will be instructed to turn right on 10th Street, left on M Street and then right or left on 11th Street, depending on their desired direction. Southbound drivers on 11th Street will be prohibited from turning right on L Street and will be directed to M Street instead. Access to businesses located in the 1000 block of L Street will be maintained.
