Electronic signs warning of delays were in place along the freeway, and traffic was backed up for several miles, Markham said. Drivers could take a short detour along the Old Road, which runs parallel to the freeway, she added.

"There is absolutely no issue with the structural integrity of the bridge," she said. "It is in no way impacted. People absolutely should not be concerned because if a Caltrans bridge is open, it is safe."
