The Baltimore Street Bridge will be reduced to a single-lane of traffic on Monday, to allow for a biannual inspection of the bridge. The contractor will begin work at 8 a.m. and conclude at 5 p.m. Parking on the bridge will be prohibited during those hours. Each end of the bridge will be flagged to direct vehicles around the contractor’s equipment. Traffic patterns across the bridge are expected to be restored by 5 p.m. on Monday.
