Wolf Administration Announces Work to Begin on Route 100 (Pottstown Pike) Safety Improvement Project in Chester County


​King of Prussia, PA – The Wolf Administration announced today that construction is scheduled to begin Monday, February 19, on a project to improve traffic flow and safety along a 6.3-mile section of Route 100 (Pottstown Pike) in Upper Uwchlan, West Vincent, East Nantmeal and South Coventry townships, Chester County.

“Improving vital infrastructure like Route 100 in Chester County will include modern safety enhancements to alleviate congestion and move traffic safely through this critical corridor,” Governor Tom Wolf said.
Over the next several months, crews will work to improve the stretch of Route 100 (Pottstown Pike) between Garrison Drive and Route 23 (Ridge Road). The scope of work includes resurfacing the corridor with an open-graded surface treatment (NovaChip) to increase friction and reduce hydroplaning; constructing two shoulder-widening pull-offs; and installing pavement markings rumble strips, and guiderail.
In addition, PennDOT’s contractor will improve the intersection of Route 100 (Pottstown Pike) and Route 23 (Ridge Road) by constructing a dedicated northbound left-turn lane as well as updating traffic signals.
Beginning Monday, February 19, through Friday, February 23, from 9:00 AM to 3:00 PM, motorists will encounter lane restrictions in both directions on Route 100 (Pottstown Pike) between Black Horse Road and Route 23 (Ridge Road), for clearing operations.
Motorists are advised to allow extra time when traveling through the work zone because slowdowns will occur during construction. The contractor's schedule is weather dependent.
Allan A. Myers, LP, of Worcester, Montgomery County, is the general contractor on the $5.6 million project, which is financed with 100 percent federal funds. The entire project is scheduled to be completed in late summer.
