This was a design decision from PennDOT at this point, based on the driveways that need to be maintained north of Park Avenue and maintain access for them as well as Timber Lane.
Once you get 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 north of Fox Court at that point and otherwise connect it to that neighborhood network.
The roundabout itself has traffic calming effects with reduced speeds and whatnot, for people to traverse the roundabout in the first place 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.
Everything on West Highland Avenue heading west is all stop-controlled intersections and that is done by Langhorne Manor borough at this point too. 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 413 and getting on the ramps there. All the traffic that was local traffic will obviously still be going through the local network to get to Route 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, we will continue to develop the EA (Environmental Assessment) document through the summer and publish it this fall. We anticipate an environmental decision next 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 to take 18 to 24 months, which would put us in 2029 for a construction start. That’s based on where we are currently at. The construction would be anticipated to take 3 construction seasons or 3 years. We really have not gotten into detail on the construction schedule yet, but we are anticipating 3 construction seasons or 3 years.
There is one roundabout at the southern end of 413 with west Highland Avenue, Bellevue Avenue and Pine Street, the flashing signal, and then the mini roundabout on the other side that’s proposed at Gillam Avenue and Bellevue Avenue.
Those are the two at cloverleaf. Then the other one is the third one at the south end with the north bound ramp connections for Highland Avenue and the northbound ramps for Route 1.
There was a speed study done previously with the RC 1 and RC 2 projects up through RC 3 and based on that analysis it was determined to keep the speed limit at 55 MPH through this section. So, it will not be reduced but a section will open up to make it a little bit safer and more recoverable and more area for vehicles to move off the road, but the speed will not be reduced because it is 55 MPH south of there and 55 MPH north of there.
The bridges will all be replaced as currently scoped, and the four bridges being replaced are US 1 over Highland Avenue, which is the only mainline Route 1 bridge. Then, the West Interchange Road overpass over US 1 will be replaced.
The bridge carrying PA 413 or Pine Street over Route 1 US 1, will be replaced. And then at the northern end Corncrib Lane Overpass, which is also known as Devot Drive for Woods School, will be replaced also.
Additionally, there is the reinforced concrete culvert that was discussed that is also being looked at to be replaced.
There is a portion there that we kind of touched on earlier (part of the access road North of Hulmeville Avenue to Hill Avenue) that would remain. But the other portion north of Hill Avenue to Station Avenue will be able to be removed and converted to green space or a shared use trail that we were looking at.
Where a service road is to remain in place, that would be barrier separated with median barrier from the main line shoulder. If it’s to be removed and converted to green space we would be able to put in guide rail along that edge of shoulder instead of barrier, but obviously nothing is getting closer to the lawns as they are today, so that existing service road pavement footprint will just be converted to lawn.
Yes, Route 1 will remain a four-lane divided highway, limited access highway, as it currently is today.
Our traffic study does begin starting 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, I believe they are referencing Saint Mary’s Medical Center, that’s north of where our project will be affecting traffic patterns, so we didn’t go up quite that far. Then at 213 it goes from Old Lincoln Highway to South Flowers Mill Road.
We have had meetings with Our Lady of Grace Cemetery regarding access to their property. They consider the frontage along US 1 as the main entrance, and we were told by them that their funeral procession uses the frontage road as it currently is and comes down from 413 to the cemetery entrance and that is the access they prefer to use.
The access off of Old Lincoln Highway they consider their back entrance. The portion from T-336, Parkvale Avenue, to the cemetery entrance will end up being converted to a two-way driveway for the cemetery, so that they can maintain their processionals as they currently are. Again, that was based on coordination with the cemetery directly.
