The fire was burning east of Discovery Bay Boulevard on both sides of the highway, authorities said. Heavy smoke has reduced visibility in the area to nearly zero, according to reports.
Smoke from the fire prompted the California Highway Patrol to shut down Highway 4 while crews battled the fire.
#DiscoveryBay , #Hwy4 both directions at #OldRiverBridge, shut down because of a grass fire creating near-zero visibility. Alternates #Hwy12 and #I205 are so far away, maybe better to wait it out.#KCBSTraffic
