Temporary closure of Sewickley Bridge to occur during repairs

Thursday, August 8, 2019 | 11:30 AM

Sewickley Bridge construction, slated to begin in 2020, will result in significant traffic changes.

According to PennDOT spokesman Steve Cowan, preservation work is anticipated to begin in late April or early May.

“We do not currently have a finalized construction schedule, but the project will only be a single season,” Cowan said in an email.

The draft plan, which can be altered, includes nightly single-lane restrictions for preparatory work, weekend closures, and one 10-to-14-day full closure of the bridge. Cowan said the project has not been bid, and timeframe discussions for the full closure will not occur until PennDOT has secured a contractor.

In cooperation with the Federal Highway Administration, PennDOT District 11 will conduct a meeting regarding the project from 5 to 6:30 p.m. Aug. 15 in the Sewickley Public Library’s community room. Representatives will discuss the bridge project’s scope, traffic plan and schedule, and residents can ask questions.

The preservation project includes an overlay of the bridge deck, replacement of bridge deck joints, bridge approach slabs and pavement improvements to the approaching roadway, he said.

This entails removal of the existing bridge deck wearing surface and replacement with a latex-modified concrete wearing surface; replacement of existing neoprene strip seals and compression seals; re-setting of a bridge bearing and the construction of new bridge approach slabs. The project includes full-depth rehabilitation on both the Moon and Sewickley approaches, according to a PennDOT notice shared by Sewickley Borough Manager Marla Marcinko.

The current bridge structure, which spans the Ohio River between Sewickley Borough and Moon Township, was built in 1981, making it 38 years old, said Cowan.

“This preservation project is necessary in order to ensure the life of the bridge deck, as well as the bridge superstructure,” he said.
