PennDOT will be busy in the Lehigh Valley during the 2026 construction season, working on the Hill to Hill Bridge, Interstate 78, Route 33 and Route 309, among others.

PennDOT District 5, which includes the Valley, will improve more than 197 miles of road and 77 bridges, the agency announced Thursday. The total investment in the six-county area is more than $1.2 billion.

“Our district continues to address critical infrastructure needs of this growing region,” PennDOT Engineering District 5 Executive Chris Kufro said. “These projects will not only upkeep the roads and bridges but also keep them safe for the many drivers who use them.”

Some of more notable projects that will begin or continue this year include:

In multiple counties

• Rehabilitating the Route 378 Hill to Hill Bridge over Norfolk Southern Railroad, city streets, Delaware & Lehigh Trail, and the Lehigh River in Bethlehem, about $74 million. The project will include adding a new parallel span along the southern half of the bridge for northbound traffic to help alleviate traffic congestion.

• Replacing the Route 329 Cementon Bridge over the Lehigh River in Whitehall Township and Northampton, $21.7 million.
