PHILADELPHIA, PA — Drivers traveling through the busy intersection of Allegheny Avenue and Delaware Avenue in Northeast Philadelphia should prepare for long-term congestion beginning Tuesday, May 26, as PennDOT launches utility construction tied to the massive I-95 Section AF3 improvement project.
At a Glance
- Roads Affected: Allegheny Avenue and Delaware Avenue
- Dates: Tuesday, May 26, through late April 2027
- Times: 24 hours a day, seven days a week
- Reason: Utility construction and I-95 interchange improvements
According to PennDOT, the Allegheny Avenue and Delaware Avenue intersection will be reduced to a single travel lane for approximately one year.
Initial work will include flagger-controlled lane closures and temporary traffic stoppages while crews install construction barriers and temporary traffic signals at the intersection.
Once activated, the temporary signals will guide a single lane of traffic through the work zone around the clock while utility construction continues. The signals will also stop traffic in both directions during train crossings at the intersection.
Motorists traveling through the area should expect significant backups and slower traffic conditions throughout the project. Drivers are encouraged to allow extra travel time and seek alternate routes whenever possible.
The utility work is part of PennDOT’s $311.3 million I-95 Section AF3 project, which includes reconstructing and widening both directions of I-95 to four lanes near the Allegheny/Castor Interchange and reconfiguring the interchange to add new northbound ramps at Castor Avenue.
PennDOT said the existing Castor Avenue on-ramp will remain open except for two or three future weekend closures that will occur during later construction phases.
Section AF3 is the third of four major contracts tied to the larger reconstruction and modernization of the I-95 Allegheny/Castor corridor. The overall project is scheduled for completion in late 2031.
