YOUNGSTOWN — Interstate 680 near Glenwood Avenue, which had been closed since a Monday afternoon crash that damaged a bridge pillar for the Mahoning Avenue Bridge, reopened Thursday night, said Chuck Shasho, Youngstown’s deputy director of public works.

The Mahoning Avenue bridge over I-680, which has also been closed since the crash damaged the pillar, is expected to remain closed for six to eight weeks, Shasho said.

Shasho said his information came from the Ohio Department of Transportation, which has hired a contractor to make repairs and has been installing separation walls on I-680 to facilitate the interstate’s reopening.

Shasho and Youngstown Mayor Jamael Tito Brown made the announcement Thursday afternoon.

Shasho said that after I-680 reopens, the city will be recommending the following detour routes:

• Westbound: Marshall Street to I-680 to Meridian Road south to Mahoning Avenue.

• Eastbound: Entering I-680 at the “Mahoning Avenue ramp” and exiting at Glenwood Avenue, which allows a motorist to get back to Mahoning Avenue by making a right turn onto Glenwood Avenue.

Shasho said after I-680 is back open, the city will put up semi-permanent detour signs to help people navigate the detours.
