Traffic was blocked on Highway 37 and Highway 4 after accidents, and roadwork on Highway 121 required a detour Thursday.
From Bay City News:
(BCN) Westbound state Highway 37 in Vallejo has reopened after being shut down for hours this morning because of a fiery crash that killed a big-rig driver, a California Highway Patrol spokesman said.
A collision between an Ace Hardware big-rig and a white pickup truck was reported at about 6:40 a.m. on westbound Highway 37 just east of state Highway 29, CHP Officer Chris Parker said.
The collision caused the big-rig to fall from the overpass, Parker said. It landed in a grassy area below and caught fire.
Parker said two witnesses who were driving north on Highway 29 saw sparks coming from the big-rig before it fell from Highway 37.
