Highway 99 reopens after hay truck fire cleared

All lanes of Highway 99 have reopened after crews finished clearing away tons of hay that burned on the back of a flatbed truck Monday.

The all-clear message was posted on the CHP’s Traffic Incident Information Page at 9:14 p.m. -- nearly 8 hours after the fire was reported at 1:22 p.m.

The blaze closed southbound Highway 99 for part of the afternoon as 25 tons of hay burned and smoldered, sending out thick plumes of smoke that blurred visibility and snarled the rush-hour commute.

Traffic backed up for about 5 miles to the interchange with Highway 50, and left some motorists stranded in traffic for hours.

By late afternoon, one lane had re-opened and traffic was moving slowly.

No injuries were reported. The cause of the fire remains under investigation.
