Pennsylvania Department of Transportation, Engineering District 6-0
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.
Right-of-way support consisting primarily of deed research.
Environmental Permitting assistance.

SCI is designing a number of projects as prime consultant. Tasks include Survey, Environmental, Hydrology/Hydraulics, Permitting, Structure Design, Roadway Design, and preparing bid packages. Projects include:
Raccoon Park Road Bridge over Traverse Creek, Raccoon Creek State Park, Beaver Co.: This project was the replacement of the existing structure with a new 75’ single-span prestressed concrete spread box beam bridge with scour protection. Formliners and concrete staining were included to enhance the bridge appearance. The approach roadways were also reconstructed.
Rockport Road over Buck Mountain Creek, Lehigh Gorge State Park, Carbon Co.: This project is the replacement of the existing structure with a new 53’ single-span prestressed concrete spread box beam bridge on a 35° skew with scour protection. Formliners and concrete staining were included to enhance the bridge appearance. The approach roadways will also be reconstructed. Due to the need to maintain access at the Park, a temporary roadway and stream crossing will be constructed.
Trout Run Road Culvert over Trout Run, Tiadaghton State Forest, Lycoming Co.: This project is the replacement of the existing corrugated metal pipe arch with a new 24’ x 10’ precast concrete arch. Formliners and concrete staining were included to enhance the bridge appearance. The approach roadways will also be reconstructed.
Yarrison Road Bridge over Fourth Gap, Tiadaghton State Forest, Lycoming Co.: This project is the replacement of the existing structure with a new 16’ x 8’ precast concrete arch. Formliners and concrete staining were included to enhance the bridge appearance. The approach roadways will also be reconstructed.
Lebo Road Culvert over Big Spring Branch of Lebo Run, Susquehannock State Forest, Potter Co.: This project is the replacement of the existing steel pipe arch with a new 15’ x 7’ precast concrete box culvert. Formliners and concrete staining were included to enhance the bridge appearance. The approach roadways will also be reconstructed.
Park Entrance Road & Access Road to Lot #4, Gouldsboro State Park, Monroe Co.: This project is the reconstruction of 2800’ of the Park roadway by reclaiming the existing pavement as new base and resurfacing with bituminous pavement.
On-lot Sewage Treatment Facilities, S.B. Elliot State Park, Clearfield Co.: This project is to obtain the on-lot sewage permit for a new shower house/comfort station with sandmound treatment facility to service the Park’s rental cabins. The site is located within a High Quality (HQ) watershed.
Bear Meadows Road Bridge over Sinking Creek, Rothrock State Forest, Centre Co.: This project is to rehabilitate the existing 21.5’ single-span steel I-beam bridge by installing steel diaphragms and spot painting the steel beams, replacing the laminated wood deck and bituminous paving, and place rock slope protection.
Fee Hollow Road Bridge over West Branch Cowley Run, Sizerville State Park/Elk State Forest, Potter Co.: This project is to rehabilitate the existing corrugated steel plate arch by underpinning the gabion headwalls, placing rock riprap for scour protection and update roadway signing.
UNT to Bushkill Creek/Camp William Penn Lake Culverts, Delaware State Forest, Pike Co.:This project is to replace 2 existing culvert structures with precast concrete box culverts. The approach gravel roadways will be repaired as need and a trail may be realigned as part of the project.
