This 100-foot span simply supported pedestrian bridge over Market Street consists of two 60-inch deep AASHTO girders spaced at 9'-8" apart that are joined at the bottom flanges with a 5-inch reinforced concrete slab. Its southwest end bears on a 20-foot high retaining wall. Its northeast end bears on a 5-foot by 13-foot reinforced concrete pier with 10" walls on a pile supported footing. A reinforced concrete slab spanning 22 feet connects the northeast end of the main span with a reinforced concrete helical ramp structure.
