King of Prussia, PA – Northbound and southbound Route 309 (Sellersville Bypass) motorists will encounter long-term and short-term lane closures through three separate work zones in West Rockhill Township, Bucks County, for various construction activities under a project to rehabilitate the pavement and repair several structures on a 9.1-mile section of the expressway, the Pennsylvania Department of Transportation (PennDOT) announced today.

The work schedule and locations are:

  • Monday, May 23, through Monday, June 13, from 7:00 PM to 6:00 AM the following morning, a lane closure will be in place on northbound and/or southbound Route 309 (Sellersville Bypass) between Route 152 (State Road) and Lawn Avenue for barrier removal;
  • Monday, May 23, through Friday, July 15, a 24/7 lane closure is scheduled on northbound and southbound Route 309 (Sellersville Bypass) between Lawn Avenue and Rich Hill Road for pavement repair; and
  • Monday, May 23, through Winter 2023, from 9:00 AM to 3:00 PM, a periodic lane closure will be in place on northbound and/or southbound Route 309 (Sellersville Bypass) from Route 152 (State Road) to just north of Reliance Road for the rehabilitation of two bridges.

Motorists are advised to allow extra time when traveling through the work areas because backups and delays will occur. All scheduled activities are weather dependent.

Under this project, PennDOT's contractor will reconstruct and rehabilitate the Route 309 corridor (Sellersville Bypass) from Unionville Pike in Hatfield Township, Montgomery County, to just north of Rich Hill Road in Richland Township, Bucks County. The improvement plan includes the following:

  • Milling and overlay;
  • Reconstructing shoulders;
  • Installing new guide rail and median barrier;
  • Replacing two bridge superstructures;
  • Rehabilitating eight Route 309 bridges, four overhead bridges and four culverts;
  • Repairing concrete ditches;
  • Installing drainage improvements, new pavement markings and signs; and
  • Integrating Intelligent Transportation Systems (ITS).

James D. Morrissey, Inc. of Philadelphia is the general contractor on the $54.6 million project, which is financed with 80 percent federal and 20 percent state funds. The entire project is scheduled to finish in summer 2024.
