ROSELAND, Calif. (AP) — Authorities say they had to block vehicles from entering a gas station near Santa Rosa after a computer problem had gas there on sale for 39 cents a gallon.

Sonoma County sheriff’s deputies and the California Highway Patrol responded to a traffic jam at the 76 station in Roseland around 8 p.m. Thursday.

Sheriff’s Sgt. Kevin Scanlon described the scene as a “blockade” as drivers tried to get in on the cheap gas. Gas in Santa Rosa is averaging about $3.36 a gallon.

Scanlon told the Press Democrat of Santa Rosa the station planned to close for the night, so the computer problem could be fixed.

A station employee declined to comment on how much gas was sold at the 39-cent price.
