The Pennsylvania Department of Transportation (PennDOT) reports to motorists on the status of its High-Speed Interchange project between I-80 and I-99 that will enhance traffic safety by providing a direct connection between the two highways.

Shoulder reconstruction and widening on I-80 eastbound and westbound between mile markers 158 and 163 will now start at 6:00 PM Sunday, September 29. The contractor will reduce traffic to one lane between 6:00 PM and 6:00 AM to minimize traffic impacts while completing this work.

Work will begin in the westbound lanes and continue for approximately a month before switching to the eastbound lanes for another month. All work is weather dependent.

PennDOT initially announced this work would begin earlier in the month, but there were delays.

Overall work on this project includes building the interchange, ten bridges, four retaining walls, five box culverts, seven sign structures, and three changeable message boards. It also includes constructing new and rebuilding existing roadways and ramps, drainage improvements, installing Intelligent Transportation Devices, guide rail and highway lighting, pavement marking, stream improvements, and miscellaneous construction. Work will continue through the next six construction seasons, ending in 2030.
