A big-rig driver making a U-turn in San Leandro caused a messy fuel spill this morning, an Alameda County fire spokeswoman said.
A stretch of Marina Boulevard between Alvarado and Merced streets was blocked to traffic after the spill, as was southbound Alvarado Street, police said.
The spill was reported at about 6:50 a.m. after the driver of a big-rig exiting Interstate Highway 880 went the wrong way on Marina Boulevard and attempted to make a U-turn, fire spokeswoman Aisha Knowles said.
The driver had meant to go west but instead headed east, she said.
While attempting to turn around, the driver struck part of the center divider, she said.
The fuel-carrying saddlebags on the side of the truck were damaged, and 90 percent of the fuel inside was spilled onto the roadway, Knowles said.
The driver continued down the road briefly before stopping, she said.
Firefighters and police responded, along with the county's hazardous materials team, Knowles said.
Crews were able to stop the fuel from spreading beyond the affected area, and around 10:30 a.m. firefighters left the scene. A cleanup company was then dispatched to mop up the mess, Knowles said.
