PennDOT to Begin Route 41 (Gap Newport Pike), Route 926 (Street Road), Roundabout Safety Improvement Project in Londonderry Township, Chester County


King of Prussia, PA – The Pennsylvania Department of Transportation (PennDOT) announced today that construction will begin Monday, January 22, 2024, on a $6.3 million project to construct a roundabout at the Route 41 (Gap Newport Pike) and Route 926 (Street Road) Intersection in Londonderry Township, Chester County.

Under this contract, PennDOT's contractor will construct a single-lane, four-legged roundabout slightly south of the existing intersection alignment to improve safety, increase mobility, and accommodate future traffic demands.

Due to the nature of the roundabout construction, existing pavement at the current intersection will be removed. Route 41 (Gap Newport Pike) will be reconstructed and resurfaced for approximately 1,900 feet and Route 926 (Street Road) will be realigned for approximately 1,400 feet. The agricultural land to the west of the roundabout, between the existing and relocated portions of Route 926 (Street Road), will be used for stormwater management. To the east of the roundabout, the existing Route 41 (Gap Newport Pike) will be vacated and replaced with a proposed wetland mitigation area.

In addition to stormwater management improvements, the project will include reconstructing the roadway approaches; relocating driveway access; and installing roundabout lighting, signage, and pavement markings.

Beginning, Monday, January 22, through late October 2024, Route 926 (Street Road) will be closed and detoured between Route 41 (Gap Newport Pike) and Route 796 (Jennersville Road).

During the closure, motorists are directed to use Route 41 (Gap Nepwort Pike) and Route 796 (Jennersville Road).

Drivers are advised to allow extra time when traveling near the work area because backups and delays will occur. All scheduled activities are weather dependent.

During this first stage of construction, in additon to the Route 926 (Street Road) closure, Route 41 (Gap Newport Pike) motorists will encounter lane shifts onto the existing northbound shoulder, enabling a temporary barrier to be placed along the outside edge of southbound Route 41 (Gap Newport Pike).

During stage two, both Route 41 (Gap Newport Pike) and Route 926 (Street Road) will be closed and detoured.

J. D. Eckman, Inc. of Atglen, PA, is the general contractor on this project, which is financed with 100 percent federal funds.

This roundabout project is part of several improvement projects planned on Route 41 (Gap Newport Pike) in Londonderry and London Grove townships and Avondale Borough, Chester County. For more information on the Route 41 (Gap Newport Pike) and Route 926 (Street Road) roundabout project and other projects planned for Route 41 (Gap Newport Pike), please visit the Route 41 project website.
