Project Information

PA 41 at Route 926 Intersection

Project Description

The proposed project consists of intersection improvements to the PA 41/Route 926 intersection in Londonderry Township, Chester County. The preferred alternative consists of a single-lane, four-legged modern roundabout. The roundabout will be located slightly south of the existing PA 41/Route 926 intersection. The roundabout will serve as a traffic calming measure to reduce the speed of vehicles entering the roundabout.

The project also involves the reconstruction and overlay of PA 41 for approximately 1,900 feet and the reconstruction of Route 926 for approximately 1,400 feet. The agricultural land to the west of the proposed roundabout, between the existing and relocated portions of Route 926, will be used for stormwater management, and the existing PA 41 roadway to the east of the proposed roundabout will be vacated and will be replaced with a proposed wetland mitigation area.

Project Schedule and Next Steps

The project’s design phase has been completed. The environmental document prepared for the project can be found at this link: CE Expert System.

Final design activities have been completed. The construction plan is shown to the right.

The Project was awarded to JD Eckman, Inc. of Atglen, PA, on November 15, 2023. The Construction phase began on December 7, 2023.

A virtual public meeting to discuss the details of construction will be scheduled in the near future. Details for this meeting will be posted on this website.

Traffic During Construction

The project will be constructed in two stages. During Stage 1, the majority of the new roundabout, as well as the western Route 926 approach and the southern PA 41 approach, will be built offline behind a temporary concrete barrier. The PA 41 travel lanes will be shifted onto the existing northbound shoulder, enabling a temporary barrier to be placed along the outside edge of PA 41 southbound pavement. Route 926 between PA 41 and Route 796 will be detoured during this stage using the detour route shown in Figure 1. In Stage 2, both PA 41 and Route 926 will be detoured using the detour routes shown in Figures 2 and 3. This will enable the remainder of the roundabout to be constructed along with the eastern Route 926 approach and northern PA 41 approach.
