VALLEJO (CBS SF/BCN) — A truck carrying 3,800 gallons of diesel flipped over on Highway 37 in Solano County Tuesday near a marsh area, authorities said.

The crash was reported shortly before 6 a.m. near Skaggs Island Road. Both directions of the highway remained closed as of shortly after 11 a.m. while crews work to transfer fuel from the overturned tanker onto another carrier so the big-rig can be put back on its wheels, Caltrans and CHP officials said.
