The purpose of this project is to facilitate safe and efficient travel within and through the project study area to meet current and future transportation needs while providing a functional and modern roadway that meets driver expectations.
What is the status of PennDOT’s current preferred alternative, and where does the project currently stand?
The project is currently in the process of beginning additional (more detailed) environmental reviews through an Environmental Assessment. This began in November 2024 and will involve additional public involvement, including a public hearing.
What are the anticipated opportunities for public involvement/comment for this project?
We anticipate additional virtual plans display (via this project website) and a virtual public meeting in 2025 as part of the Environmental Assessment process. Invitations and announcements will be made once the public meeting has been scheduled. Comments can be submitted at any time via the comment section of this website, email to info@us1bucks.com, or in writing to:

Will additional travel lanes be added to PA 413 (Pine Street) north of Flowers Avenue?
This project will not widen PA 413 (Pine Street) north of Flowers Avenue. Additionally, PennDOT does not have any plans for the future widening of PA 413 (Pine Street) through Langhorne Borough.
Will the project increase traffic on PA 413 (Pine Street) north of Gillam Avenue?
The project will not significantly increase traffic on PA 413 north of Gillam Avenue. It is anticipated that some traffic will redistribute between the existing PA 213 (Maple Avenue) interchange and the proposed PA 413 (Pine Street) interchange.
However, since there are already connections between U.S. 1 and PA 413 via Bellevue Avenue and Gillam Avenue in the area of the proposed interchange, traffic is not expected to increase significantly based on the Delaware Valley Regional Planning Commission’s Regional Travel Model and PennDOT traffic analysis.
Will the RC3 project increase traffic on Gillam Avenue in Langhorne?
Overall, the RC3 project will result in minor increases in traffic on Langhorne Manor’s Gillam Avenue. It is anticipated that traffic will redistribute along Gillam Avenue at each intersection based on driver destinations.
Based on updated PennDOT traffic analysis completed in 2024, AM peak hour traffic is projected to see a 29% increase, which is an average increase of 50 vehicles per intersection for the nine (9) intersections studied along Gillam Avenue, and the PM peak hour is anticipated to see a 17% increase, which is an average increase of 35 vehicles per intersection for the nine (9) intersections studied along Gillam Avenue.
Almost all of this increase is expected to be east of the intersection with West Interchange Road, with the largest increase occurring at the intersection with Pine Street due to the new interchange. It is expected that the increase will be mostly local traffic that previously used the frontage road, now traveling to the newly constructed interchange.
Operationally, the most affected stop-controlled intersections are projected to still operate with minimal delay. At the same time, the internal neighborhood roads will see a decrease in cut-through traffic as traffic is redistributed onto the collector and arterial roads. PennDOT is also investigating additional traffic-calming treatment options along Gillam Avenue.
Will the RC3 project increase truck traffic through Langhorne Borough?
The RC3 project will not significantly increase truck traffic through Langhorne Borough. It is anticipated that some truck traffic that currently utilizes the existing PA 213 (Maple Avenue) interchange to travel north on PA 413 (Pine Street) will redistribute to the proposed PA 413 (Pine Street) interchange. This would allow the trucks to avoid making tight right turns at the intersection of PA 413 (Pine Street) and PA 213 (Maple Avenue) and allow a straight-through movement. These projections are based on the Delaware Valley Regional Planning Commission’s Regional Travel Model and PennDOT traffic analysis.
Has PennDOT performed traffic counts for the PA 213 (Maple Avenue) / PA 413 (Pine Street) intersection, and what was the truck volume?
PennDOT’s traffic count data from February 2024 showed 8 Heavy Trucks and 104 buses/single unit trucks (or 112 total trucks/buses) in the morning peak hour and 6 Heavy Trucks and 49 buses/single unit trucks (or 55 total trucks/buses) in the afternoon peak hour.
PennDOT’s online traffic count data from 2024 indicates 3% truck traffic and 511 total trucks and buses along PA 413 (Pine Street) north of the intersection, and 12% truck traffic and 1522 total trucks and buses along PA 413 (Pine Street) south of the intersection.
Will PennDOT be performing additional traffic counts to ensure they have the latest data?
As part of the Environmental Assessment, PennDOT conducted additional traffic counts in winter 2024 throughout the entire project area to ensure as accurate an assessment as possible of the existing traffic conditions along the entire project corridor.
Are any traffic signals being added to PA 413 (Pine Street)?
Two new traffic signals will be added along PA 413 (Pine Street) as part of this project. One traffic signal will be at the intersection of PA 413 (Pine Street) with the proposed U.S. 1 northbound ramp and Woods Drive, and the second traffic signal will be at the intersection of PA 413 (Pine Street) with the proposed U.S. 1 southbound ramp and Gillam Avenue. The traffic signals will control and direct traffic through these intersections. Crosswalks and bicycle/pedestrian facilities will be provided for and accommodated at these intersections.
