Big rig hits 5 Freeway overpass in Sun Valley, knocking down chunks of concrete and closing lanes

A big rig hit an overpass Friday morning on the 5 Freeway in Sun Valley, prompting the closure of the two right lanes while Caltrans cleared chunks of concrete and checked the extent of damage to the bridge.

The crash was reported to the California Highway Patrol at 9:41 a.m. Friday on the southbound 5 Freeway at Sheldon Street.

A witness told the CHP the big rig hit the overpass and that large chunks of concrete were in lanes.

The CHP issued a SigAlert for the two right lanes of the southbound Golden State Freeway and Caltrans planned to follow that with a hard closure to assess structural damage and clear debris. The HOV and lanes 1 and 2 were open. Lane 3 was reopened at 11:21 a.m., but the far right lane remained blocked.
