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.).
