PennDOT District 11 is announcing single-lane restrictions on northbound Route 28 in O’Hara Township, City of Pittsburgh, and Aspinwall Borough, Allegheny County will begin Wednesday, September 21 weather permitting.

Beginning at approximately 6 a.m. Wednesday, single-lane restrictions will occur on Route 28 in the northbound direction from the Delafield Avenue off-ramp (Exit 7) to the Blawnox off-ramp (Exit 9) around-the-clock through mid-October. Crews from Swank Construction Company will perform roadway reconstruction and paving operations.

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.
