SANATOGA PA – If you’ve been driving on U.S. Route 422 near Sanatoga during the past week, flashing electronic signs posted there have been difficult to ignore. Their message: prepare for some consistent traffic disruption, beginning Monday (Sept. 24, 2012).
And lasting for six years.
Work gets started Monday night, according to the King of Prussia office of the Pennsylvania Department of Transportation, on a six-year-long project “to rebuild and improve” 1.6 miles of 422, from about a mile west of the Armand Hammer Boulevard Interchange to the Route 724 Interchange.
The $73.3 million project includes replacing worn pavement and two structurally deficient bridges. The cost is being financed with 80-percent federal and 20-percent state funds.
The reconstruction will start simply enough. Drivers on 422 West in Lower Pottsgrove Township will find its right lane closed nightly through Saturday (Sept. 29) from 7 p.m. to 7 a.m. between the Sanatoga and 724 exits for “shoulder work,” PennDOT said.
However, that’s just a sliver of the efforts planned by the agency’s contractor, J.D. Eckman Inc. of Atglen PA in Chester County. In the bigger picture, through October 2018, its crews will:
- Replace bridges over the Schuylkill River, Norfolk Southern railroad spur and Norfolk Southern mainline tracks;
- Replace the Armand Hammer Boulevard Bridge over Route 422;
- Improve and realign the ramps at the Armand Hammer Boulevard Interchange; and
- Reconstruct the Route 724 ramp to eastbound Route 422.
Also to be replaced: the Armand Hammer Boulevard bridge over 422, seen here from the TriCounty Business Park looking north to the Antonelli Medical and Professional Institute.
They will also install:
- Three new overhead sign structures;
- Conduit for future Intelligent Transportation System equipment;
- Two new traffic signals;
- A wetland mitigation site;
- Storm water management improvements;
- New median barrier and glare screen;
- New guide rails 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, PennDOT said.
There’s also more ahead, it warned. 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.
In a related matter, PennDOT also warned motorists on 422 East and West that, again beginning Monday and continuing through Saturday, a different contractor – Independence Constructors – will conduct bridge cleaning between the Royersford and Stowe interchanges across Limerick and Lower Pottsgrove townships and the borough of Pottstown. That work will be done during daylight hours from 9 a.m. to 3 p.m.
