This project will not widen PA 413 (Pine Street) north of Flowers Avenue. Additionally, PennDOT does not have any plans for future widening of PA 413 (Pine Street) through Langhorne Borough.
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 Delaware Valley Regional Planning Commission’s Regional Travel Model and PennDOT traffic analysis.
Traffic signals will be added at the two new intersections on PA 413 (Pine Street) with the proposed US 1 NB and SB ramps as well as Woods Drive 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 with these intersections.
The PennDOT design team investigated proposed roundabouts at the PA 413 / proposed U.S. 1 ramp intersections and found that due to traffic flow patterns, specifically at the PA 413 / U.S. 1 SB ramp intersection, proposed roundabouts result in traffic queuing (backing up) onto U.S. 1 during peak travel times within 10 years (2035). As such, roundabouts at these intersections are no longer being considered.
Yes, the project provides the following proposed pedestrian and bicycle accommodations:
- A 12-foot-wide path is proposed along the east side of PA 413 (Pine Street) within the project limits to connect the existing sidewalks north and south of the project.
- 5-foot-wide paved shoulders will be provided on the West Interchange Road overpass.
- In areas where the existing frontage (service) roads are no longer needed, the design team is investigating replacing the existing pavement with a shared-use (pedestrian and bicyclist) path. This is being done in coordination with the local municipalities. As of now, Middletown Township has voiced its support for including a shared-use path while Langhorne Manor Borough has requested to not have the path within its respective boundaries.
A detailed noise study is being completed for the project. If warranted, reasonable and feasible in accordance with PennDOT Publication 24, noise walls will be proposed as part of this project. In areas where noise walls are proposed, the local impacted property owners will have a vote on whether to accept the noise wall. A simple majority will determine whether the potential proposed noise wall will be incorporated into the project.
Construction is currently scheduled to begin in late 2026. Due to the complexity of the proposed project, construction is anticipated to take three years to complete.
In areas where the frontage (service) roads are needed for access to adjacent properties, they will be retained but disconnected from U.S. 1. In areas where existing frontage roads are no longer needed, the design team is investigating replacing the existing pavement with a shared-use (pedestrian and bicyclist) path. This is being done in coordination with the local municipalities. In areas where frontage roads are no longer needed, the adjacent connecting local roads will be terminated with hammerhead turnarounds. Hammerhead turnarounds are being proposed instead of cul-de-sacs to minimize impacts to adjacent property owners.
Modern roundabouts are not the same as traffic circles and provide significant safety and operational improvements over traffic circles. Please watch the video at the following link for further explanation. https://youtu.be/nNXRlWgAVOg
If your property (or a portion of your property) is needed for the project, a PennDOT representative will contact you once plans have been prepared for the Acquisition of Right-of-Way in the final design phase of the project. See the brochure below for more information.
PennDOT and the project team provide updates through the www.US1Bucks.com website.
It is anticipated that 3 acres of impervious surface will be removed and converted to green space as part of this project.
PA 413 (Pine Street) is federally classified as a Regional Principal Arterial. This classification of roadway is meant to carry most trips entering and leaving the area and serves intra area travel. In the existing condition, U.S. 1 traffic must exit the mainline via frontage roads and then disperse onto neighborhood streets and then travelers work their way to a major street (e.g. Pine Street) to continue or complete their trips. Providing a direct connection to PA 413 (Pine Street) via an interchange reduces traffic on neighborhood streets and places vehicles directly onto PA 413 (Pine Street) via a modern interchange design.
Current practice is to provide 16’-6” of clearance for a bridge over a highway like U.S. 1. PA 413 (Pine Street) is posted for a minimum clearance of 13’-11” and has been accidentally struck previously, most recently on April 12, 2022, by under-passing trucks.
- First and foremost, the project addresses safety by closing the intermediate access crossovers between the frontage roads and U.S. 1. These locations are known to have a high crash frequency.
- Secondly, the project replaces the concrete separator islands with proposed 12-foot to 14-foot-wide paved shoulders and concrete median barriers. These improvements provide safe pull-off areas for disabled vehicles as well as keep errant vehicles on U.S. 1.
- Lastly, the project replaces the remaining three overpasses on U.S. 1 between I-295 and the I-276 (PA Turnpike) that have deficient vertical clearance, which reduces the likelihood of vehicles striking the overpasses.
PennDOT is only able to restrict truck traffic based on engineering justification (e.g., deficient vertical clearances, bridge weight limitations, pavement structure) or due to traffic conditions. PA routes and primary highways are generally not posted with truck restrictions and are preferred highway facilities to accommodate truck traffic (in comparison to neighborhood streets).
Changes to designation of PA 413 is not part of this project. The designation or redesignation of PA 413 would involve the Bucks County Planning Commission and the Delaware Valley Regional Planning Commission in coordination with PennDOT and other regional stakeholders. Any redesignation of PA 413 needs to examine regional travel patterns, which are beyond the scope of this project. With the availability of modern traffic routing tools and smartphone applications, such a redesignation would likely have a minimal effect on traffic volumes passing through Langhorne Borough.
PennDOT and their design consultant engineer previously completed an initial high-level investigation into both a tunneling option and also a potential depressed roadway alternative with access (bridge) crossings. The initial investigations had the cost of tunneling in the range of $900M to $1.3B based on similar projects nationwide. The initial investigations into a depressed roadway (excluding capping with green space) were in the range of $300M to $400M. Additionally, future maintenance would also need to be taken into account, which is considerably higher for an underground facility when compared to a typical at-grade roadway. Lastly, detailed studies/reports were not completed for either option to determine constructability/feasibility.
Access will be provided at all times during construction to residences and businesses along U.S. 1 (Lincoln Highway) and any of the intersections where construction takes place.
If your home or business is within the RC1 corridor and lies in the path of construction, you likely already have been contacted by PennDOT or one of its authorized representatives. Property owners and businesses impacted within the RC2 corridor will likely be contacted in the near future. Final design has not yet been determined for RC3. Whatever the case, owners are always fairly compensated by the Commonwealth for property that is needed for infrastructure improvements.
To limit congestion, queues, and delays due to construction, 2 lanes of traffic will be maintained in both directions on the U.S. 1 mainline and along Street Road from 5am to 9pm. Based on experience along the corridor, traffic will be able to be reduced to 1 lane in each direction from 9pm to 5am, when traffic volumes are much lower.
At certain times throughout the life of the project, 15-minute rolling traffic stoppages are anticipated to allow for overhead work such as bridge demolition, bridge beam installation, overhead sign structure truss installation, etc. These traffic stoppages will be limited to occur during overnight hours when traffic volumes are the lowest.
Bristol Road is anticipated to be the only long term detour for construction of the Bristol Road Overpass. Bristol Road will be detoured via Rockhill Drive, Old Lincoln Highway and Neshaminy Boulevard during reconstruction of the Bristol Road overpass.
Due to high traffic volumes and the need to maintain 2 lanes of traffic in each direction on U.S. 1 from 5am to 9pm, certain construction operations will be restricted to nighttime work when additional working room (i.e. additional lane closures) is necessary. PennDOT will attempt to limit the amount of nighttime work permitted through requirements included in the contract documents.
The construction duration within the RC1 corridor is currently anticipated to take approximately 4 years total, through 2022; however, it should be noted that this schedule is subject to factors such as utility relocations, weather, etc.
If you encounter potholes and other maintenance concerns at any time on Pennsylvania’s roadways, simply call PennDOT’s toll-free Roadway Maintenance Hotline, 800-FIX-ROAD, to report the problem and its location. We’ll take it from there.
Use the form on the Contact Us section of the website at any time with your questions or concerns about the construction operation. We will respond usually that same day or shortly thereafter.
Sound barrier will be placed between the Roosevelt Cemetery property and U.S. 1 SB, Ramp AB, and Ramp B, and between the Faulkner property and the Roosevelt Cemetery property.
During the ongoing final design process, the RC2 and RC3 corridors are being evaluated for noise mitigation, including sound barriers. At locations where sound mitigation is called for, PennDOT will hold special purpose meetings to present those plans and gather feedback from affected residents who will be notified by mail of the meetings.
The time and location for each open house public plans display meeting (for RC2 and RC3) will be publicized in advance through local media and on the project website: www.us1bucks.com. We’ll also share information about upcoming meetings with the municipalities and your local state representatives. For special purpose meetings such as those to discuss sound barriers, residents within the noise impact study will be notified by mail.
PennDOT’s engineering team is working to solidify plans for the RC2 and RC3 Sections of U.S. 1. As these plans are being finalized, PennDOT will hold open-house plan displays in the community to give residents a chance to see the plans taking shape, comment on the plans, or ask questions related to anything on the plans. As these plans are finalized, we’ll update the website’s content and graphics.
