Chesapeake City Bridge Miscellaneous Repairs

This project will consist of all multiple repairs and maintenance activities necessary for the repair of the Chesapeake City Bridge.   The bridge is located along MD Route 213 in Chesapeake City Maryland.   Anticipated work on the bridge will consist of superstructure steel and approach slab repairs.  Repairs will include replacement and repainting of severely deteriorated and corroded primary steel members near leaky deck joints, lateral bracing connection plates, main span arch ribs and gusset plates.  Heavy to severe pack rust exist between the floor-beam bottom flange angles and the ends of the bottom flange cover plates at several locations.  This pack rust has resulted in cracked welds between the bottom flange cover plate and bottom flange angles at some locations.  Numerous stringers in the South Approach spans exhibit holes in the webs over the floor-beam top flange bearing areas including a large hole, 12" long x 1" high, exists in the lower web of a stringer.  The inspection walkway has areas with disconnected handrail due to deterioration.  Numerous holes and cracks are present in the concrete substructure and roadway.  The south approach slab is in poor condition with extensive patches and associated spalling.  The curbs at both approaches display heavy deterioration and the blunt end of the northwest curb is a hazard to traffic.  Both the repair of the south approach slab and the curbs along both approaches will be repaired.
