The southbound  I-5 was temporarily reduced to one lane for several hours on Saturday morning due to a big-rig that had leaked diesel across four of the five lanes on the freeway.

A Sigalert was put into place at Calgrove Boulevard shortly after 5 a.m., according to California Highway Patrol officials.

“There was a big-rig that had a punctured fuel tank,” said Sgt. Haggard. “It spilled diesel across the No. 2, 3, 4 and 5 lanes. Everything but the fast lane.”

About two hours into the cleanup, he said, traffic was alleviated when cleanup crews were able to open the No. 2 lane.

Shortly after 8 a.m., the cleanup was continued.

“They finished cleaning it at 8:10 a.m.,” Haggard said. “It’s cleaned up. all lanes are open.”

The freeway was reopened at 8:26 a.m., but as off 9:34 a.m., traffic is still down to nine miles per hour at Calgrove Boulevard.
