The single, temporary northbound lane on the Birmingham Bridge will be closed from 8 a.m. to noon tomorrow while crews remove conflicting lane markings.

Traffic will be detoured to the Hot Metal Bridge. Southbound traffic will not be affected at that time.

However, the on-ramp from Forbes Avenue to the Birmingham Bridge in the southbound direction will be closed from noon to 5 p.m. when the work moves there. Traffic will be circled through South Oakland via Craft Avenue and Fifth Avenue and back to the bridge.
