Longfellow Bridge Rehabilitation

MassDOT Boston-Cambridge, MA: Lead Engineering Firm for Accelerated Techniques for the restoration of the Longfellow Bridge. Constructed in 1908, this bridge consists of eleven original open-spandrel steel arch spans and two steel girder approach spans at the Cambridge approach. The bridge has an overall length of 2,135 feet, and a deck width of 105 feet, which includes a 27-foot fenced median occupied by the MBTA Red Line. Gill’s role on the project includes detailed bridge inspections during construction and the structural design of the steel girder approach span superstructure replacement, a gantry crane system used for movement of materials and equipment for the superstructure rehabilitation and a temporary shielding system to protect the MBTA Red Line during construction.  Gill was also responsible for performing QC reviews for the design team.
