Construction Method and Specifications
McB provided construction engineering services in support of Phase 1 girder erection in a narrow area between the existing bridge and active Metro-North Railroad tracks. This phase included conventional girder erection over land with ground based crawler cranes in addition to 4 spans of girder erection over the Housatonic River.
The proximity of the existing railroad bridge eliminated the option of using barge mounted cranes for the river spans. McB developed an innovative procedure where girders could be erected from the existing bridge using lightweight truck cranes and rolled laterally on temporary supports. This system utilized temporary towers, rolling carts, and an external stiffening truss to provide girder stability until all girders and cross frames were erected in a particular span.
