A Chicago drawbridge

The 1927 double leaf Adams Street Bridge is one of Chicago’s moveable bridges that lift for boat traffic along the south branch of the Chicago River.

Back in the 19th century, the downtown Chicago River was the city’s main harbor, filled with Great Lakes vessels during the navigation season. In 1955, Adams Street was converted to a one-way for westbound Route 66 traffic. Today, the city schedules twice-weekly bridge openings for pleasure boats, to avoid interrupting downtown traffic.
