Firefighters contained a two-alarm fire early Tuesday morning in the Rio Vista area.
The fire spread rapidly near Highways 12 and 160, which splintered into multiple fires that involved crews from Isleton, Montezuma, River Delta, Fairfield, Suisun City and Contra Costa County Fire responded to help.
Hwy 12 was closed due to the response, but is now back open.
Power lines were also down in the area, but customers had it turned back on around 6 a.m.
The cause of the fire is unclear, as of now.
