Until October 14, 2007 there is complete closure of the lower roadway of the Manhattan Bridge. There is no access to the lower roadway during construction from either end of the bridge. All traffic is directed to the upper roadways. Two lanes are maintained both Brooklyn bound and Manhattan bound at all times for all type vehicles. The north bikeway was closed October 9, 2006 through August 2007 and pedestrian cyclist access across the bridge is maintained by sharing the south walkway during this period. Train service is not interrupted.
