Temporary support, demo & erection plans for Sullivan County bridge 192

This project consisted of the removal of an existing two-span, steel multi-girder with timber deck bridge superstructure, partial removal of the existing concrete abutments, and removal of the existing pier.

Construction consisted of a new two-span galvanized steel multi-girder superstructure with composite concrete deck on concrete integral abutments and a concrete solid stem pier founded on steel piles, along with related approach and drainage work.

A temporary bridge was required to maintain single lane alternating one-way traffic at all times with traffic lights controlling traffic.

R. DeVincentis Construction contracted with Delta to provide demolition plans for the existing bridge, temporary bridge substructure, GRSS wall, and cofferdam designs, as well as erection plans for the new steel multi-girder bridge system.
