Chicago River bridge gets stuck after lifting for boat to pass

A major bridge in downtown Chicago remained stuck in a raised position for over four hours on Wednesday. The malfunction occurred after the bridge was lifted to allow a boat to pass, resulting in significant traffic congestion throughout the city's downtown area.

Reports indicate that the mechanical failure was caused by extreme heat, which led the bridge's components to expand and prevented it from lowering. The incident disrupted transit for several hours before the structure was eventually restored to its normal position.
