CTDOT West River Bridge Replacement

New Haven & West Haven, CT

AI is providing survey and construction inspection services for the replacement of bridge no. 00163 over the West River and the reconstruction of the adjacent I-95 mainline and ramps in the cities of New Haven and West Haven. This assignment required establishing horizontal and vertical photogrammetry and project control, locating existing bridge piers, abutments and superstructure, as well as locating wetlands, soil borings and topographic survey for adjacent streets, including property and utility research and preparation of complete survey plans. Finally, AI coordinated with Ocean Surveys, Inc. to perform Bathymetric survey of the Moses Wheeler section of the Housatonic River. River bottom spot shots and contours were generated using GPS technology. AI survey also captured as-built borings in the Housatonic River at proposed bridge pier locations.
