The Columbus Drive Bridge  ( 300 east and 400 north ) crosses the main branch of the Chicago River 3/10 a mile west of the river mouth.   Currently it is the world’s second largest bascule bridge.   It was built in 1982.   Cost of construction was $33 million. The largest span is 269 feet.  Total length  is 389 feet.   Deck width is 89.8 feet.

It is a single piece box truss similar to the Loomis Street Bridge.  There are 8 trusses 4 in each leaf.    During its short history, there have been two incidents involving the bridge:  1 April, 15, 1983 cracks were found in three of the gears;  May, 1984  bridge failed to open due to binding of the center bolt.
