Pittsburgh, PA – PennDOT District 11 is announcing a traffic crossover on southbound Route 28 in O’Hara and Harmar townships, Allegheny County, will begin Friday, September 9 weather permitting.

A southbound crossover on Route 28 will be implemented Friday at approximately 8:00 p.m. continuously through 5 a.m. Monday morning between the area adjacent to the Hulton Bridge and Alpha Drive as crews conduct paving operations. To accommodate this work, the following traffic configuration and restrictions will occur: 

• Traffic heading southbound on Route 28 will be crossed over into a single northbound lane half a mile south of the Harmar Interchange (Exit 11)

• Northbound traffic on Route 28 will be maintained. Traffic will be placed in a single-lane configuration beginning just north of the Blawnox Exit (Exit 9)

• Access to RIDC Park (Exit 10) from southbound Route 28 will be closed, requiring a detour.

• Access to southbound Route 28 from RIDC Park will also be closed, requiring a detour.

• Motorists will be placed in a stop condition on the RIDC Park ramp to northbound Route 28.

• The Freeport Road on-ramp to southbound Route 28 from Blawnox remains closed through mid-September. Traffic is detoured (see detour information below)

The work is part of the $15.32 million project to improve approximately 3.5 miles of Route 28 between the Delafield Avenue exit (Exit 7) and the Harmar Township line, approximately 1.75 miles north of the RIDC Park (Exit 10) interchange. Construction will include minor road widening of the southbound lanes near the Freeport Road on-ramp (Exit 8) interchange to allow for the existing lanes to be reassigned. At the completion of the project, southbound Route 28 will maintain two through lanes and an exit only off-ramp to Fox Chapel Road. Work includes reconstruction of the Delafield Avenue ramps, concrete preservation work on the Fox Chapel ramps, milling and paving work on the RIDC Park ramps, and bridge preservation work on all structures within the project limits. Additionally, highway lighting upgrades, ITS upgrades, green stormwater features, guide rail upgrades, rockfall area cleanouts and fence repairs, and other miscellaneous construction are part of the project. Single-lane restrictions will occur with crews maintaining at least two lanes of traffic in each direction during peak travel times and at least one lane in each direction during off-peak hours. Ramp closures will occur as needed, with many occurring overnight. The project is expected to be completed at the end of 2022.
