PennDOT is set to begin installing wrong-way detection technology along Route 28 on Monday.
The technology will be added to off-ramps in Pittsburgh, Millvale, Sharpsburg, Etna, Aspinwall, Shaler, O’Hara and Harmar.
Shoulder restrictions will occur weekdays from 9 a.m. until 3 p.m. at the Millvale exit through Friday. Officials will provide closure updates as crews work on different locations.
The $4.8 million safety detection project will target 21 ramps along a stretch of Route 28 that saw 30 wrong-way crashes between 2019 and 2023.
Crews will install cameras, lights, infrared technology, radar and sensors to detect vehicles driving in the wrong direction on Route 28 ramps.
Officials expect it will be completed by next spring.
