A crane working on Interstate 8 near El Cajon struck a utility line and started a small fire early Tuesday.
The crane operator was working in eastbound lanes of I-8 near 2nd Street just before 4 a.m. when the vehicle struck the utility line crossing the interstate.
Officers say the crane was moving one of the concrete barriers when the boom of the crane hit a line.
Firefighters quickly extinguished a fire that sparked during the incident. No one was injured.
California Highway Patrol officers did not close any additional lanes to traffic. The two far-right lanes were already closed down for the overnight construction project.
The crane involved has the logo of the same rental company that was involved in a similar incident last week.
A truck crane from Lakeside-based Bob's Crane tipped over on State Route 15 south when the operator was moving a K-rail. In that incident, the operator was injured.
No further information was immediately available.
