Bridge Documentation

View Archived National Bridge Inventory Report - Has Additional Details and Evaluation

This bridge and the adjacent highway bridge were built in 1948 as part of the creation of Broadmoor Avenue, a direct route for M-37 from 28th St & East Beltline Ave to Caledonia (about 8 miles SSE). They are the result of local topography, as all the other roads (and a few rail spurs since removed) crossed it at grade. Broadmoor Avenue has since been widened to 5 or more lanes to the north, and the highway has a divided section to the south. Approaching the bridge on Broadmoor Avenue, this bridge looks like a through plate girder (girder and floorbeam system). However looking at the bridge from underneath, it is apparent the bridge is composed of multiple parallel built-up beams (multi-girder/stringer bridge) although the outermost beams are a little taller like a through plate girder would have, and the railings for the bridge are mounted on these taller beams.
