At least one person suffered major injuries today in crash on Highway 99 in Merced involving six vehicles, including two big-rig trucks, the California Highway Patrol reported.
It was not immediately clear how many people were hurt, officer Jason Schoonhoven said.
One person who suffered major unspecified injuries was air-lifted to an area hospital, the CHP said.
Northbound traffic is shutdown on Highway 99 at R Street. Vehicles are being diverted onto V Street and over to 16th Street. The section of Highway 99 is expected to remain closed until some time after 1 p.m., the CHP said.
Only northbound lanes are affected, Schoonhoven said.
The CHP said road construction was under way in the area of the crash, which was reported at 10:47 a.m.. The work may have been a factor in the collision.
"It appears that one vehicle in the fast lane did not stop for vehicles in front of them that were already stopped for construction and a chain-reaction collision occurred," Schoonhoven said.
Two big-rig trucks were involved in the collision, along with two pickups, a white van and a sedan, the CHP said.
More information will be reported as it become available.
