Traffic remains in chaos on San Mateo roads

By 10:15 a.m., westbound state Route 92 was clear of cars, but traffic was still cut off along the busy artery as crews worked to sweep up spilled lye without polluting the air or bay.

A three-truck accident closed all of westbound 92 just before 7 a.m. today, cutting off a major Bay Area artery and causing backups along the regions other bridges and roadways.

A 6:57 a.m., a flatbed truck carrying pre-mixed concrete and lye crashed into a disabled big-rig on the right shoulder of the San Mateo Bridge. The back end of the flatbed swung into the middle lanes where it was “T-boned,” by a UPS big-rig, according to California Highway Patrol Officer Mike Davis.

The driver of the flat-bed was thrown from the vehicle had to be airlifted from the scene with major injuries and his passenger and the driver of the disabled big rig were both taken in ambulances to local hospitals for treatment.

At 10:30 a.m., traffic along southbound 880 was stopped dead from San Leandro to the 92 off-ramp, and Davis said all ramps leading onto westbound 92 from 880 were closed. Davis said two of the trucks were clear by 11:00 am, and they hoped to have the third moved before noon to allow traffic across the westbound half of the bridge.

“We have it contained, but we don’t want the debris to get into people’s lungs because there’s lye in it, so we’re sweeping it up instead of using mechanical means,” Davis said.

Three people were taken to local hospitals with injuries sustained in the crash. The driver of the secondtruck involved in the accident was ejected from his vehicle and had to be airlifted from the scene. His passenger, and the driver of the first vehicle – a stalled big-rig – were taken by ambulance for treatment.
