Ramp from Highland Park Bridge to southbound Route 28 closing Tuesday

A long-term closure of the ramp from the northbound Highland Park Bridge to southbound Route 28 in Sharpsburg will start Tuesday, weather permitting, PennDOT has announced.

According to PennDOT, the ramp will close at about 7 a.m. Tuesday and remain closed to traffic around-the-clock through mid-December.

Crews will be doing reconstruction work, bridge rehabilitation and drainage improvements on the ramp.

Traffic to southbound Route 28 will be detoured.

The posted detour will be:

• Take Route 8 north;

• Turn right onto the 62nd Street Bridge;

• Take the ramp to Route 28 via Sharpsburg;

• Continue straight on Bridge Street;

• Turn left onto the ramp to southbound Route 28.

The ramp work is part of a $47.31 million project addressing the existing bottleneck and congested traffic on Route 28 at the Highland Park Bridge interchange. Work started in late 2020 and is expected to be finished in 2023.

The project involves the reconstruction of Route 28 between North Canal Street/Kittanning Pike and Delafield Avenue; the establishment of two travel lanes in each direction through the interchange; and the reconstruction of acceleration and deceleration ramps.

It also features the reconstruction of ramps at the Highland Park Bridge/Freeport Road interchange; bridge and wall preservation work; roadway widening; sound barrier installation;, and various operational and safety improvements.
