A motorcyclist was taken to a hospital by medical helicopter with major injuries after crashing on westbound state Highway 4 in Brentwood on the morning of Sept. 10, according to the California Highway Patrol.
The crash was first reported at 6:41 a.m. in the area of the Sand Creek Road off-ramp.
CHP officers initially believed multiple vehicles may have been involved, but later determined the motorcyclist crashed without hitting any other vehicles.
All westbound lanes of the highway shut down while the helicopter picked up the motorcyclist for transport to the hospital. The lanes reopened by about 7:25 a.m., according to the CHP.
