Beginning August 18, 2010, contractors will close one stairwell at Civic Center Station for about four weeks. The contractors will close the stairwell at 8th and Market (near the Hotel Whitcomb) to replace a granite wall with a steel railing. This work is being done at the request of the City of San Francisco. The contractor expects to finish the project by September 15, 2010. During the construction, the contractor will erect temporary chain link fences and temporary lighting. BART apologizes for any inconvenience this project may cause.
