All lanes of State Route 92 just west of San Mateo were blocked Wednesday morning after an overturned big-rig was pulled from the road and its load of gravel that had spilled was swept up, according to the California Highway Patrol.
The truck fell over just after 7:30 a.m. near where State Route 92 meets Skyline Boulevard, between the Lower and Upper Crystal Springs reservoirs, CHP officials said.
One lane of traffic was closed on State Route 92 while crews pulled the truck upright and cleaned up the spill. The road was reported to be fully open again as of about 9:45 a.m., according to the CHP.
No one was injured in the crash.
