Wildfire Destroys Bridge Over Colorado River Near Arizona-California Border

A bridge crossing the Colorado River in southwestern Arizona collapsed on July 28, 2026, after catching fire during a wildfire near the state’s border with California. The structure, located on Hart Mine Road near Cibola, failed as flames from the Island Fire reached the crossing, according to reporting from AZ Family.

Island Fire damages Hart Mine Road bridge

The collapse occurred on July 28, 2026, as a result of the Island Fire. The wildfire burned through the region near Cibola, Arizona, eventually reaching the bridge that spans the Colorado River on Hart Mine Road. AZ Family reported that the bridge caught fire before the structural failure led to its collapse.

The bridge serves as a critical crossing point for the Hart Mine Road corridor. The fire’s progression through the brush and timber in the southwestern border region created the conditions that compromised the bridge’s integrity.

Impact on Cibola regional infrastructure

The loss of the Hart Mine Road bridge disrupts transit across the Colorado River in this remote section of Arizona. Because the bridge is a primary link for local access and utility movement in the Cibola area, the collapse creates a significant gap in the regional transportation network.

Emergency crews and fire officials have been managing the Island Fire’s spread across the Arizona-California border. The fire’s ability to destroy a river crossing highlights the intensity of the blaze in the rugged terrain of southwestern Arizona.
