The Maple Avenue interchange with U.S. 1 will remain in its current state. That intersection was reconstructed in 2014 and will remain open during construction.
The RC3 project will add an auxiliary lane to the intersection, which will add a weave lane between the Route 213 interchange and the Route 413 off-ramp interchange. You would still enter U.S. 1 from Route 213, Maple Avenue.
This was a design decision made by PennDOT based on maintaining access to the driveways north of Park Avenue and Timber Lane. Once north of Fox Court, there is no property access onto the service road heading north, so there is no reason to continue the service road at that point.
The proposed roundabout at West Highland Avenue has traffic calming effects that will reduce speeds for drivers traversing the roundabout, especially with this being a standard roundabout at this location.
No additional measures are currently being looked at beyond what is shown on the plan at this point. Traffic heading west on West Highland Avenue encounters stop-controlled intersections that are controlled by the Langhorne Manor borough.
Within the confines of the project limits, we are doing as much as we can to slow and calm down traffic heading onto West Highland Avenue.
That was part of our origin-destination study to determine where cars are coming from and going to, and we found that the traffic impact is minimal; all the traffic will be filtering through to Route 413 and its ramps. All local traffic will continue to use the local network to access U.S. 1. Our analysis still shows acceptable levels of service and delay, and no major increases at any of the intersections in the network.
Based on our current level of progress with the Environmental Assessment (EA), we will continue to develop the EA document through the summer and publish it this fall.
We anticipate an environmental decision in the summer of 2026, which, at that time, assuming it’s a finding of no significant impact, we would shift into the final design/right-of-way acquisition phase of the project.
We anticipate that to start early in 2027. We anticipate that phase to take 18 to 24 months, which would put us in 2029 for a construction start. The construction is anticipated to take 3 construction seasons or 3 years. Details on the construction schedule will become available closer to the construction start date.
One roundabout will be built at the southern end of Route 413 and connect with West Highland Avenue, Bellevue Avenue, Pine Street, and the flashing signal.
This roundabout will connect with the proposed mini roundabout at Gillam Avenue and Bellevue Avenue. Those roundabouts are at the cloverleaf.
The third one at the southern end will connect with the northbound ramps for Highland Avenue and U.S. 1.
There was a speed study done previously under the RC1 and RC2 projects through the RC3 area, and based on that analysis, it was determined to maintain the speed limit of 55 MPH through this section.
The RC3 project will increase safety on U.S. 1 by widening the roadway and shoulders. These improved conditions will allow motorists to maintain a speed of 55 MPH throughout the entire corridor.
The following four bridges will be replaced, not rehabilitated, as currently scoped:
Additionally, there is the reinforced concrete culvert that was discussed during the meeting that may be replaced.
Part of the access road north of Hulmeville Avenue to Hill Avenue will remain. The other portion, north of Hill Avenue to Station Avenue, will be removed and converted to green space or a shared-use trail.
A barrier-separated service road is to remain in place, with a median barrier from the main line shoulder. If it’s to be removed and converted to green space, a guide rail would be installed along that edge of the shoulder instead of a barrier. Nothing is getting closer to the lawns as they are today, so the existing service road pavement footprint will just be converted to green space.
Yes, U.S 1 will remain a four-lane, divided, limited access highway, as it currently is today.
Our traffic study starts from south on 413 at the Bellevue intersection, and it continues north on Pine Street up to Winchester Avenue. It doesn’t go all the way up to Saint Mary’s. The study does not go to Saint Mary’s Medical Center, north of where our project will be affecting traffic patterns. At Route 213, the study goes from Old Lincoln Highway to South Flowers Mill Road.
