PennDOT has announced 31 projects that are expected to start during the 2026 construction season, and will continue in 2026 in the four-county region. Officials say they anticipate investing more than $200 million in the region, which encompasses Washington, Fayette, Greene and Westmoreland counties. This investment includes rehabilitating, reconstructing, and resurfacing 99 miles of highways, as well as improving 48 bridges – 27 through preservation, three through rehabilitation, and 18 through replacement. In Washington County, some of that work will include the Route 18 over Catfish Creek project which will replace the structure carrying Route 18/South Main Street, over a branch of Catfish Creek in the City of Washington. That is expected to cost two-point-two-million dollars. A second project involves the I-70 Bentleyville to Route 519 Preservation project. Crews will mill and pave I-70 and the ramps at the Route 519/84 Interchange, Dunningsville Interchange, and Kammerer Interchange. The project will also include base repair, drainage upgrades, and raising the bridge that crosses Route 519, and will cost between twenty-million and twenty-five-million dollars.
