A large truck carrying 12,000 pounds of onions fell on its side at the tight curving ramp between the southbound Golden State (5) and eastbound Pomona (60) freeways, the California Highway Patrol reported.
The mishap blocked ramps to both the Pomona and Santa Ana (5) ramps, and the CHP diverted all southbound 5 traffic to the westbound Santa Monica (10) Freeway for more than two hours. Caltrans workers were called in to remove the onions.
The crash happened at 6:23 a.m., and at 7:45 the CHP was calling in more barricade trucks to block the ramp for a long closure.
Although five freeways tie together at the East L.A. Interchange, only southbound Golden State traffic was affected. The interchange is billed as the largest in California, and was dubbed "Malfunction Junction'' decades ago by longtime KNX traffic reporter Bill Keene.
