A $46.5 million and two-year project, located in Franklin Park Borough and Marshall Township of Allegheny County, Pa., entered the active construction phase in late August 2025 and continues to make progress through the cold winter months.
Exit 73, off of I-79 at the Route 910 Wexford Interchange and located just two mi. north of the I-79/I-279 split, currently faces significant congestion including daily queuing and spillback. With reduced flow of mobility as well as an influx of accidents within the past few years, the interchange required a long-term solution to accommodate traffic demands — both for now and in the future.

The approved Wexford Interchange project offers many benefits, including reduced car crashes, less congestion and queuing, as well as shortened commute time. In addition, the current SR 910 bridge structure can remain intact and preserved without the need of complete replacement. Altogether, these benefits save money, time and enhances overall community safety.
Project Details
According to PennDOT, the finished project will include a new full offset single-point urban interchange (SPUI), two new flyover structures and bridge preservation and rehabilitation including substructure repairs, bearing replacements and deck overlay. Also, two large overhead cantilever sign structures and a retaining wall will be installed, as well as roadway widening, drainage work, guide rail updates, milling, new highway lighting, traffic signal improvements and more.
The SPUI, a compact highway intersection controlled with a single traffic light, combines two intersections into one and gives opposing traffic the ability to turn left while reducing traffic and diminishing wait time. This interchange is ideal in tight and highly congested areas and is expected to reduce accidents and the number of blockages, which commonly occur within the community given the existing conditions.

The Wexford Interchange project spans approximately a mile and a half — starting north of the I-79/279 split and stretching to Mingo Road, which is north of the 79/910 interchange, through Route 910 and Wexford Bayne Road, as well as between Nicholson Road, Brandt School Road and VIP Drive, located in Franklin Park Borough and Marshall Township of Allegheny County, Pa.
The contractor awarded the nearly $47 million project, Golden Triangle Construction Company Inc., began construction in August 2025. Golden Triangle Construction, a prominent general utility contractor and heavy/highway contractor in western Pennsylvania and based out of Imperial, Pa., expects to reach project completion by October 2027.
Project Progress
All preliminary engineer work, environmental clearances, final design, contractor selection and pre-phase work has been completed in the past two and a half years. Recent pre-phase work included installing a barrier along 79 for construction protection, as well as constructing the left shoulder off I-79, ramp C and ramp D. Ramp C, Exit 73, is the northbound I-79 off-ramp to Route 910/Wexford and ramp D is the on-ramp from Route 910 to northbound I-79.
Roadway widening, removal of old signal equipment and pole removal are in process.

While traffic is temporarily moved to I-79 Northbound off-ramp and the I-79 Southbound.
Once completed, Golden Triangle Construction Company plans to next build a temporary off-ramp on the northbound side, construct a pier and abutment and remove a median curb on Nicolson Road and Wexford Bayne Road.
Starting early spring, beam installation begins with intermittent stoppages and overnight closures with a ramp detour. The new flyover ramps are expected to open by early 2027 while the old ramps are removed. Next, final paving, striping, polyester polymer concrete overlay and stormwater devices will be installed and implemented.
Although the construction of the Wexford Interchange project creates minor time delays and setbacks, the completed project will offer travelers and daily commuters a safer, more efficient route, with less complexity and significantly less spillback and traffic. CEG
