ALLENTOWN, Pa. -

The northbound lanes of the Eighth Street Bridge will be closed Thursday from 9 a.m. to 3 p.m.

PennDOT officials say that cement trucks will be making delivers there to repair the bridge, so northbound traffic will be detoured on St. John Street, South Sixth Street, West Wyoming Street, South Fifth Street, Auburn Street, Lehigh Street, Union Street, South Sixth Street and Linden Street.

The southbound lanes of the bridge have been closed since the project to rehabilitate the bridge began in May.

Pedestrian traffic and emergency vehicles will be accommodated.
