Winds gusting at high speeds knocked down several trees in the Bay Area early Thursday morning including a 2,000-pound Eucalyptus that fell along eastbound Interstate Highway 80 in Pinole causing a driver of a rig carrying a truckload of wastewater to crash into it.
California Highway Patrol Officer Steven Fajardin said the driver struck the tree about 3 a.m. and was OK after the collision.
The accident caused a Sig-Alert, blocking three lanes of traffic until about 6 a.m.
Other trees fell along Trimble Road in San Jose, in Petaluma and Sonoma.
