"This bridge is among the older of the bascule bridges in Chicago whose trusses are configured such that the bridge is partly a pony truss and partly a deck truss.

Few specific designs of bridges have lasted as long as 60 years, but this unusual deck/pony trunnion bascule design sure did, and as such it was obviously a successful design."

Constructed in 1922
