Work Areas Shift along Route 403 Corridor as Long-Term Improvements Project Continues in Somerset County

The Pennsylvania Department of Transportation (PennDOT) today announced that Plum Contracting, Inc., of Greensburg, will continue safety improvement work in various areas of Route 403 starting Monday, July 10, 2023, in Conemaugh Township, Somerset County.

On Monday, the contractor is expected to begin bridge preservation work in a new location of Route 403. Along with channelizing devices, portable traffic signals will be set up to control single-lane closure at the north and southbound ends of the work zone on Route 403, at the entrance of the Conemaugh Townships Municipal Authority, and at the entrance to Conemaugh Township EMS.

This set up will be in place through August 4, 2023. Work taking place during this time includes removal and replacement of existing bridge parapets, structure repairs and other associated construction. Installation of new drainage facilities may also take place during this period.

Similar work this week also began on July 5, with traffic signals set up at Chestnut Street (T-768), the entrance to Varner Auto Sales and Lion Alley. This portion is expected to be completed by August 18, 2023.

Motorists should anticipate minor delays and are advised to use caution, obey all traffic signs, signals and flaggers, and watch for construction personnel and vehicles.

This overall project will be completed over the 2023 and 2024 construction seasons, with a winter shutdown period at the end of 2023 into the beginning of 2024. It includes 6.5-miles of pavement preservation, milling, resurfacing, guide rail and drainage upgrades, and new signage and pavement markings. New curbing and sidewalks will be installed, along with upgrades to traffic signals, box culvert replacements, a new retaining wall, RC arch culvert and RC slab bridge preservations, several roadway slope stability improvements, and tree trimming and tree removal. All of this work will occur within a 13-mile stretch of Route 403 from Tire Hill to Hooversville.

The approximately $14.5 million project is weather dependent and is expected to be completed by November 2024.
