HomeMy WebLinkAboutRPT_STR 3934_Narrative_Harding Walkover over East Mt Hope_2017_1120 BIENNIAL BRIDGE INSPECTION SUMMARY HARDING WALKOVER OVER EAST MT. HOPE AVENUE STRUCTURE NUMBER – 3934 CITY OF LANSING, MI October 9, 2017 The bridge consists of a single aluminum thru-truss main span with tailspans at each end consisting of aluminum stairways with center landing. It was constructed in 1970. The bridge overall is in fair condition. DECK The bridge deck is in fair to good condition. The deck consists of aluminum grating panels welded to the bottom chord of the truss. A few of these welds are broken at the north and south end of the deck. The deck panel near the west chord connections deflects downward approximately 1/2-inch when stepped on. Steps 6 and 18 on the north stairway have cracks in the top edges. A few bolts in the stair connections were moderately rusted. There was pedestrian fencing on the sides and top of the walkway in good condition. SUPERSTRUCTURE The aluminum thru truss is in good condition. There are four bolt connections on either side for the top and bottom chord. The verticals and diagonals are all weld connected and in good condition. There appeared to be no high load marks or any signs of distress in the bottom chord. SUBSTRUCTURE The substructure consists of four steel column piers on top of concrete bases and they are in fair condition. The steel columns are in good condition with no defects. The concrete base in piers 1N and 3N have heavy map cracking with leaching on all sides. Pier 2N had minor scaling and a few vertical leaching cracks. APPROACHES The sidewalks approaching the walkway are in fair condition. Some minor vegetation was growing through the sidewalk joints. The north approach had moderate scaling. The guardrails protecting the piers along Harding Street are slightly rusted in a few isolated locations. RECOMMENDATIONS: • Patch and repair cracks in concrete pier bases. • Repair broken angles in steps 6 and 18 at north stairs. • Repair broken welds at ends of deck. • Insulate cable near the top of the main span at the north end.
