MTA Bridges and Tunnels, Biennial Inspection and Design of Miscellaneous Structural Repairs at Marine Parkway and Cross Bay Bridges
The Marine Parkway Bridge was opened to traffic in 1937. The bridge consists of a 540-foot-long center lift truss span, two 540-foot-long side truss spans and two 1,061-foot-long approaches. The Cross Bay Veterans Memorial Bridge is a precast pre-stressed concrete girder bridge with a reinforced concrete deck. The total length of the bridge is about three thousand (3,000) feet with 275 feet long main span.
SEPC performed work as a sub-consultant on the project. We performed the biennial bridge inspections, prepared inspection & flag reports for the inspected bridges, and prepared sketches using Bentley Microstation. We performed biennial inspection of the Marine Parkway Bridge and Cross Bay Blvd. Bridges for two cycles in followed by interim special inspections in in the year following regular biennial inspections.
The scope of work included review of existing documents, field inspection of structural components including floorbeams, stringers, box girders, columns, sign gantries and light standards and other miscellaneous tasks needed to complete the task. The work also included concrete sounding to remove loose or unsound concrete.
