Randolph Street Bridge

Randolph Street Bridge is a bascule bridge crossing the Chicago River in downtown Chicago, connecting the neighborhoods on both sides of the river. The structure lifts to allow boat traffic to pass through while maintaining road access when closed.

The bridge was constructed in the early 1900s to serve the growing traffic needs of downtown Chicago. It became one of several bascule bridges built along the river as the city expanded.

The bridge connects to Randolph Street, named after Edmund Randolph, the first United States Attorney General who served from 1789 to 1795.

When crossing the bridge on foot or by vehicle, be aware that it can lift without much advance notice when boat traffic requires passage. Watch for barriers and warning lights that indicate when the bridge is operating.

The bridge's lifting mechanism still operates using early 20th-century engineering technology that has been maintained in working order. This mechanical system offers a glimpse into how Chicago solved its transportation challenges when both cars and boats needed river access.
