Drivers should be alert for the new traffic pattern in place on Interstate 80 from the Shenango River Bridge to the Route 318 Bridge in Mercer County.
Under the new traffic pattern, westbound traffic is shifted onto the shoulder of the highway. One lane of eastbound traffic travels in a lane adjacent to the westbound lanes with barriers separating the two directions. A second lane for eastbound traffic is open adjacent to the work zone.
Eastbound traffic wanting to exit at the Interstate 376 interchange should use the travel lane by the work zone.
The traffic configuration is expected to remain in place for several months as construction work is done on the eastbound lanes of the highway as part of the Interstate 80 Reconstruction Project.
The overall project includes major improvements to the highway from the Ohio state line to mile marker 5, including milling, asphalt and concrete paving, concrete patching, drainage and guiderail upgrades, right-of-way fencing, concrete curbing, topsoil, seeding/mulching, highway lighting, signing, highway markers, line painting, and permanent digital message boards.
Work also includes repairs to five bridges, including the replacement and widening of the bridges over Route 318 in Shenango Township.
Construction began in April 2025 and is being completed in phases through 2027.
As part of the traffic control safety efforts, PennDOT has installed temporary traffic cameras along the interstate, which can be viewed at www.511PA.com.
Information on the Interstate 80 Reconstruction Project is available online at www.penndot.pa.gov/District1 under the Projects Near You and the District 1 link.
PennDOT urges motorists to slow down when driving in work zones, and also to be alert to changing conditions, avoid distractions and to pay attention to signs and flaggers. Drive responsibly in work zones for your safety and the safety of the workers.
