The Pennsylvania Department of Transportation (PennDOT) announced the award of a $73.3 million contract to rebuild and improve 1.6 miles of Route 422 in Lower Pottsgrove Township, Montgomery County and North Coventry Township, Chester County.

Construction will start in September from about a mile west of the Armand Hammer Boulevard Interchange to the Route 724 Interchange. Work in this phase includes the replacement of two structurally deficient bridges and replacing nearly two miles of worn pavement.

Over the next six years, crews will replace bridges over the Schuylkill River, Norfolk Southern railroad spur and Norfolk Southern mainline tracks. Crews will also replace the Armand Hammer Boulevard Bridge over Route 422 and improve and realign the ramps at the Armand Hammer Boulevard Interchange. Also, the Route 724 ramp to eastbound Route 422 will be reconstructed.

This improvement plan also includes three new overhead sign structures; conduit for future Intelligent Transportation System equipment; two new traffic signals; a wetland mitigation site; stormwater management improvements; new median barrier and glare screen; new guide rail and signs; and a multi-use trail on the bridge over the Schuylkill River.

Two travel lanes will remain open in each direction on Route 422 during peak travel times when the highway is under construction.

J.D. Eckman, Inc., of Atglen, Chester County was awarded the contract, which is financed with 80 percent federal and 20 percent state funds. Construction is scheduled to finish in October 2018.

This project is the first of six to rebuild and improve seven miles of Route 422 between the Berks County line and the Sanatoga Interchange over the next eight-to 10 years.
