The I-95 Girard Avenue Interchange project is the southernmost component of Penn-DOT’s reconstruction of I-95 in Philadelphia. This interchange is an important interface between heavily traveled I-95 and three (3) of Philadelphia’s primary arterials: Girard Avenue, Aramingo Avenue and
Delaware Avenue. The project involves:
- Reconstructing the Girard Avenue Interchange.
- Eliminating lane drops on mainline I-95 by widening from three (3) lanes to four (4) lanes through the interchange in each direction.
- Widening and reconstruction of three (3) miles of pavement and thirteen (13) bridge structures along I-95.
- Improving access between I-95 and the local street system.
- Improving highway signing.
The project has since added ITS structures along the corridor.
Susquehanna Civil, Inc. has been performing the following activities:
- Geotechnical engineering tasks such as RSGER’s, administration of core boring contracts, core boring inspection, foundation design for bridges and retaining walls.
- Field survey work for the entire project, including rail surveys and detailed information regarding all existing structures, ramps, utilities, drainage and signs. This includes surveying portions of I-95 mainline utilizing a mobile mapping solution.
- Traffic engineering in the form of all required signing and pavement marking plans.
