BENICIA — A collision along the Benicia-Martinez Bridge early Friday killed an airman with Travis Air Force Base.
The 22-year-old from Concord was killed after her Honda sedan collided into the back of a semitrailer around 6:05 a.m. on the Interstate 680 bridge.
Contra Costa CHP reports the woman was driving northbound behind a slow-moving semitrailer in the far right lane.
It appears the woman may have been speeding and was not wearing a seat belt when her car struck the back of the semitrailer.
The Honda veered across the freeway and crashed into a concrete wall.
Interstate 780 westbound and I-680 northbound were blocked off for over two hours following the collision.
CHP is still leading an investigation but reports that alcohol or drugs were not a factor in the crash.
