Based on PennDOT’s traffic studies including origin-destination studies, the proposed interchange will not induce new traffic to PA 413 (Pine Street) as a large majority of the users of the interchange live in the areas adjacent to US 1. In the existing conditions, the service roads and their intersections to Bellevue Avenue act like a de facto interchange.
The proposed interchange only allows the portion of the traffic traveling to Newtown to directly access Pine Street instead of using Bellevue Avenue and various side streets to get to Pine Street.
Any changes in traffic volume on Pine Street at the PA 213 (Maple Avenue) intersection due to the proposed interchange will be traffic that used to take the Maple Avenue interchange to get to Pine Street to travel to Newtown. Any actual increase in traffic volumes along Pine Street are likely due to redevelopment in the region (i.e., warehouses, townhomes, etc.).
It is anticipated that traffic currently exiting the Frontage Road onto Bellevue Avenue, Station Ave, Hill Ave and Hulmeville Ave to go south to Penndel, would utilize the new SR 413 Interchange in the build condition to get to Bellevue Ave.
In the no build condition, 560 vehicles in the AM peak and 575 vehicles in the PM peak are expected to pass through the Bellevue Ave and SR 413/W. Highland Ave intersection to go south on Bellevue Ave. In the build condition, for the same movement, 580 vehicles in the AM peak and 590 vehicles in the PM peak are expected. This is a difference of 20 vehicles in the AM peak and 15 vehicles in the PM peak. This minor increase in volumes during the peak hours is not expected to increase the backups due to the trains.
The increase in traffic volume along Gillam Avenue is anticipated to be 29% during the AM Peak Hour. This equates to approximately 50 additional vehicles per intersection for that one hour. All other hours of the day will see a smaller increase in traffic.
Moreso, the majority of the traffic is expected to be residents living in the area with an anticipated reduction in cut-through traffic that currently exists in the area. A traffic noise study is being completed for the project in accordance with PennDOT’s Publication 24: Project Level Highway Traffic Noise Handbook. If warranted, feasible, and reasonable, noise walls will be proposed as part of this project.
In areas where noise walls are proposed, the benefited members of the community will have a vote on whether to accept the noise wall. A simple majority will determine whether a potential proposed noise wall will be incorporated into the project. PennDOT will be responsible for maintenance of the state-owned roadways.
PennDOT has met with representatives from the Our Lady of Grace Cemetery and was told they prefer to retain access to the entrance along the existing service road. The existing service road in front of the cemetery is currently proposed to be converted to a two-way driveway to facilitate ingress and egress to their main entrance.
Improvements to East Highland Avenue are not currently part of this project.
Thank you for your input. PennDOT works to reduce impacts to adjacent properties to the extent possible and must have engineering justification to acquire property.
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.
The preferred alternative removes the portion of the service road parallel to North Street. This area will be used for stormwater conveyance in the build condition along with a potential multi-use trail.
Access to US 1 from the Fox Court area will be via the proposed interchange at Highland Avenue.
As the project is still in the initial Environmental Assessment phase of development, property impacts have not been determined at this time and are subject to change. 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. At this time, Right-of-Way Acquisition is not anticipated to begin until late 2026 / early 2027.
