A big rig that overturned tied up traffic for hours Friday morning along the southbound side of Interstate 5, just north of Laredo Highway.

The California Highway Patrol reported no injuries in the crash, which blocked both lanes for a time, but that cleaning up the mess would take 8-10 hours. The crash was reported at 1:18 a.m. Caltrans issued a Sig Alert at 5:05 a.m. and advised travellers to take alternate routes due to expected delays with cleaning up the scene.
