SR 2153 Vine St. Expy.

SJH is responsible for the rehabilitation of the bridge carrying 18th Street (SR-2153) over Vine Street Expressway (SR-0676), a single span steel welded plate girder bridge. This rehabilitation is part of a larger 4 year, federally-funded $64.8M project which began in April 2015 to replace 7 structurally deficient bridges over I-676 in Philadelphia. Construction on 18th Street is estimated to last from July 2017 until November 2019. As a subconsultant, SJH is developing girder erection plans for this structure and completing the following tasks:

• Task 1 – Prepare calculations for section properties, beam CG and pick weight for all girders in Span 1 & 2
• Task 2 – Develop calculation for stress analysis of girders while picks and in-place
• Task 3 – Develop calculation for the selection of all rigging components and wind restraints
