SR 0095, Section G4D – Interstate 95
Client: PennDOT, Engineering District 6-0
Location: Bristol Township, Bucks County, PA
Type/Size: 459′ 3-Span Continuous Curved Girder Bridge
Services: Structural Engineering
Conversion of the existing partial interchange to a full configuration by adding a ramp from southbound I-95 to SR 0413 was the primary goal of this project. PCS prepared a corridor and feasibility study that established the optimum ramp alignment. Extensive regrading within the interchange required an Earth Disturbance Permit, in addition to the usual construction permits obtained from the Pennsylvania Department of Environmental Protection for a project of this type.
The new 1.6 mile long ramp includes a new 459-foot, 3-span curved steel girder bridge that forms the third level of the interchange. The project also provided the rehabilitation of the adjacent 4-span dual-lane bridge that carries the access ramp from SR 0413 to I-95 southbound. Major items for this bridge included an LMC overlay, new expansion dams, parapet rehabilitation, and featured a seismic retrofit using a base isolation system that was one of the first of its kind used in Pennsylvania.
The project also included a 1 mile long noise wall, new guide rail and safety barriers, 3 high-mast lighting towers, and 101 conventional roadway luminaries.
