JBC is the Prime consultant providing construction inspection services during the $65 million replacement of seven existing structurally deficient bridge superstructures over the Vine Street Expressway, SR 0676 PAB, in Philadelphia. The replacements, which were planned to take place over a four (4) year period, take into account the needs of motorists, pedestrians, and cyclists. The project was designed to be completed in two stages. The first stage began in March 2015 and will be complete in time for the City’s planned Parkway Centennial Celebration starting in July 2017. The first stage includes four of the seven bridges over Interstate 676 in Center City Philadelphia; the 20th Street /Benjamin Franklin Parkway Bridge, the Pedestrian Bridge connecting Logan Circle and Vine Street at the Philadelphia Free Library, the 19th Street Bridge, and the Pedestrian Bridge connecting Logan Circle and Vine Street at the former Family Court Building. It also includes the realignment of Winter Street. Stage 2 was scheduled to start after the completion of Stage 1 and was to complete by November 2019. However, the Contractor has proposed to start Stage 2 early and agreed to advance the completion of Stage 2 to November 2018, one year earlier. Stage 2 includes the superstructure replacements on the 18th Street Bridge, the 21st Street Bridge and the 22nd Street Bridge.
Under a separate agreement with the Construction Management team for the project, JBC is providing the CPM Scheduling services during construction. Associated project work also includes new bridge approach paving; landscaping improvements; new traffic signals; new drainage; ITS elements; new pavement markings and signing; and other miscellaneous construction.
