The Holmes Walkover over East Kalamazoo Street is a single span
aluminum truss constructed in 1970. The walkover is in generally good
condition.
SUPERSTRUCTURE
The aluminum superstructure is in generally very good condition.
There is a broken bolt at the south handrail at the north stairs (top railing connection of the lower stair
run). There are two missing or broken bolts at the north railing at the intermediate landing of the south
stairs.
Some of the wire ties at the bottom of the pedestrian fencing are broken or missing (9 total counted).
At the time of inspection, there was a utility cable wrapped/tangled around the north truss support
columns.
FOUNDATIONS
The north concrete foundation pedestal for the main truss span has minor leaching cracks. The north
stair concrete foundation pedestal has leaching cracks and a shallow incipient spall on the south side.
The south concrete foundation pedestals have no deficiencies.
There is guardrail in front of both the south and north foundation pedestals. The north guardrail is low.
It also has minor dents and the east bullnose ending is bent/twisted.
RECOMMENDATIONS:
Replace broken bolt on the north stair handrail.
