A diesel fuel spillage on the 10 Freeway in West Los Angeles on Wednesday caused traffic to stop during the morning commuting hours, according to Caltrans.

A SigAlert was issued at about 7:53 a.m. near the Robertson Boulevard exit in the Palms neighborhood of L.A. 

The three right lanes were blocked as of 8:46 a.m. as crews worked to clean up the fuel spillage. Caltrans urged travelers to take an alternate route. Those routes include Venice and Santa Monica boulevards.

The lanes were reopened by 10:30 a.m., although the Robertson offramp remained closed. Caltrans indicated that traffic backed up as far as South Western Avenue.

It's not yet clear how the spillage occurred or if any injuries were reported.
