An SUV overturned early Wednesday on Interstate 880 and shut down three lanes in Oakland for nearly an hour, resulting in major traffic delays during the morning commute, authorities said.

All lanes were reopened by 7:40 a.m. after crews responded to the collision, according to the Metropolitan Transportation Commission.

The incident was reported just before 6:30 a.m. on southbound lanes near the 23rd Avenue off-ramp, the California Highway Patrol said. A Chevy Trailblazer reportedly landed on its roof.

There was no immediate information on what caused the collision.

Traffic delays were still being reported as of 7:40 a.m.
