Bridge 24B
BNSF M-CHIGAL crosses the Sanitary and Ship Canal over a former 1899 swing bridge, known as Bridge 24B during the Santa Fe days, behind a rebuilt ex-BN SD60M. This was one of eight bridges on the Sanitary between Chicago and Lockport that was converted into a moveable bridge to allow the passage of 28 Gato-class and Balao-class submarines built in Manitowoc during World War II.
