Intermittent lane closures with flagging are scheduled in both directions on Route 63 (Welsh Road) between Twining Road and Computer Avenue in Upper Dublin and Upper Moreland townships, Montgomery County, on Thursday, September 14, and Friday, September 15, from 9:00 AM to 3:00 PM, for milling and paving operations in the area of the bridge carrying Route 63 (Welsh Road) over Norfolk Southern Railroad, the Pennsylvania Department of Transportation (PennDOT) announced today. Motorists are advised to allow extra time when traveling through this work zone because slowdowns will occur during construction. The contractor's schedule is dependent on the weather. As of Tuesday afternoon, all four travel lanes on Route 63 (Welsh Road) have been reopened to motorists. In addition, westbound Route 63 (Welsh Road) motorists are able to make a left turn onto Twining Road. The bridge carrying Route 63 (Welsh Road) over Norfolk Southern Railroad is the first structure on an improvement project to rehabilitate nine structurally deficient bridges in Chester and Montgomery counties.
