Company history in st charles in Chicago, Illinois

The St. Charles Air Line Bridge is a historic Strauss Trunnion bascule bridge located at 1500 South Lumber Street in Chicago, Illinois. Originally built in 1919 as part of the St. Charles Air Line Railroad, this bridge spans the Chicago River and was constructed by the American Bridge Company. At the time of its completion, it held the world record for the longest bascule-type span. Designed by Leonard O. Hopkins, the bridge was later shortened to 220 feet in 1930 during a relocation project to straighten the river channel. This iconic structure is an important piece of Chicago's architectural history and a must-see for visitors interested in engineering marvels.
