This is being discussed with the municipalities and the public officials. Multiple forms of connections will be made to create a 4-mile loop that runs from Highland Avenue at the south end and loops along the existing service roads up to the Route 413/Pine Street connections with the proposed sidewalk. The potential loop provides various connections in areas where service roads are removed. A service road that needs to be maintained would be established on the shoulder. The road stretches north to the existing sidewalk.  This project references the Bucks County Bicycle and Pedestrian master plan that was previously created, along with other references and studies, as a basis for the concept.

Design adjustments have been made after coordinating with the school due to large gatherings. The Fairhill Avenue, Highland Avenue, and Old Lincoln Highway intersection will remain signalized for better control of traffic.

The roundabout does not impede traffic flow, especially if it’s heavy in one direction, so that should not have any negative effect on the traffic flow of a large event coming out of the school.

The intention was to look at bike and pedestrian mobility within the service roads and look at opportunities where we could remove the service roads because they are maintained by the local municipalities and not PennDOT. 

As long as the service roads are detached from U.S. 1, they can be retained, but they will not have access to U.S. 1, leaving them as local one-way connector roads.

Native American tribal consultation will be conducted as part of the project. It is going to be completed by a combination of PennDOT and the Federal Highway Administration. This is an ongoing process as part of the environmental clearance.

The study for this project started in 2011, and the initial project design was to remove the raised concrete traffic islands to eliminate the intermediate crossovers because those were where the high rates of crashes occur or have a tendency to occur.

This option would have left the access roads open at the northern and southern limits, but was extensively rejected by the public during a public plans display with then Senator Ferry at a town hall in 2014.

At that point, PennDOT decided to advance the southern two projects, RC1 and RC2, and reconsider the RC3 corridor to look at alternatives. The primary alternative was to create interchanges and close the frontage roads.

Additionally, there have been multiple fatalities along the corridor for mainline U.S. 1 traffic. There are no shoulders, so there is no recovery area for errant vehicles. There is nowhere to pull off if you have a breakdown. The raised concrete traffic islands do not prevent vehicles from leaving the highway, and there have been incidents of vehicles leaving the highway, crossing the raised concrete traffic islands, and ending up either in somebody’s front yard or in another accident along the service roads themselves.

The goal of this project is to improve U.S. 1 by providing more room for maneuverability along the mainline travel lanes. This requires an inside shoulder and a more substantial outside shoulder for vehicle refuge and concrete barriers to prevent errant vehicles from leaving the highway. Also, the West Interchange Road overpass has concrete piers in the traffic island that are a hazard and of concern.

Traffic is not projected to increase more than the current rate.

U.S. 1 would operate as any standard limited-access highway, similar to the sections north and south of the project area, for emergency vehicle access.  Intermediate access gates could also be added if discussions with emergency management services prove necessary.

A shared-use path uses a single face barrier and a grass buffer to provide a barrier between the two directions. The shared-use path can function as any type of trail accommodating bikes, pedestrians, and other non-motorized vehicles.

Removing the proposed interchange or not having any interchange in the Pine Street/Bellevue Avenue area and pushing all traffic to Maple Avenue was not studied.

Route 213 heading into the borough is heavily traveled, so moving the traffic from the Route 413/Bellevue Avenue area to Maple Avenue would greatly increase traffic and congestion at the Maple Avenue interchange. It is better to split traffic at the interchanges and make improvements to Route 413.

The previous project limit stayed out of the historic district, although Langhorne Borough brought up additional items they wanted the project to address. At the request of Langhorne Borough, the project limits were extended into the historic district. This was done to address traffic calming concerns and pedestrian access concerns between Flowers Avenue and Route 213.

From a safety perspective and the operational perspective with the traffic analysis, it was determined that a roundabout would be the preferred solution at this intersection, as opposed to a traffic signal or a stop-controlled intersection.
