Project Description
NYCDOT, as part of its efforts to extend the useful life of its bridges, is proposing necessary maintenance and rehabilitation work of the West 49th Street Bridge over AMTRAK (30th Street, Branch) between 10th and 11th Avenues in the midtown Manhattan, section of Manhattan Community District 4. The existing bridge roadway geometry consists of two westbound lanes, of which one lane has metered parking and sidewalks on each side, and one lane is for traffic on West 49th Street. The bridge is a three-span continuous steel multi girder system with a 4,100 square foot deck area which carries utilities such as electricity. The corrective rehabilitation of defective or deteriorated bridge structure components will include the removal, replacement and/or repair of: Deteriorated bridge joints and steel stringers; Concrete at underside of structural deck; Crack at wingwall; Non-standard railing/parapet and replace per current standards; Loose, deteriorated concrete at abutment wall; and Deck wearing surface. Prepare deck surface and install waterproofing. In addition, the bridge deck will be waterproofed. During the bridge rehabilitation, traffic will be maintained at all times.
