A man was killed and three other people were hospitalized after a big-rig crashed into three cars on state Highway 84 in Livermore early Wednesday morning, a police sergeant said.
The crash was reported at 4:46 a.m. between Vineyard Avenue and Vallecitos Road, according to police Sgt. Steve Goard.
The big-rig driver crashed into the three cars from behind, Goard said.
"Early indications are that traffic was slowing, and it kind of came up on him fast and he wasn't able to slow in time," Goard said.
A man in one of the cars was pronounced dead at the scene, while the big-rig driver and two other people were taken to the hospital as a precaution because of complaints of pain, Goard said.
The highway was initially expected to reopen in both directions by about 5 p.m. But Livermore police spokesperson Traci Rebiejo said later that it wouldn't be open before 7, 9 and then 11 p.m.
The road finally opened at about 10:20 p.m., police said.
Rebiejo added that the police department, which was short-handed Wednesday, was still attempting to move the vehicles and debris from the area, prompting the delay.
Police were advising motorists to seek an alternate route, such as Arroyo Road, around the scene of the crash.
