A truck overturned in Browns Valley on Friday morning, shutting down a portion of Redwood Road until late afternoon.
The truck was carrying argon and liquid nitrogen tanks that released gas when they were tipped over, according to a City of Napa spokesperson. The incident prompted a precautionary evacuation of Lynn Drive. City officials went door-to-door to warn residents within 300 feet that they should shelter in place.
The driver was not injured, according to the city. Napa Police Department announced in a Nixle alert at 4:20 p.m. that the evacuation order was lifted and the road was open.
The collision occurred on a twisting section of Redwood along a creek. Barricades were set up on Redwood at West Pueblo Avenue and at Browns Valley Road.
The truck was reported removed by mid-afternoon, leaving a city crew to repair the guardrail next to the creek.
Officials with the city, Napa Fire Department, Napa Police Department, Napa Public Works Department and Napa County Environmental Health Division were on the scene, the city said. The American Red Cross and CrossWalk Community Church assisted those affected by the crash.
Napa Police first sent out a Nixle message at 7:22 a.m., announcing that Redwood Road near Lynn Drive would be closed for an extended period due to an industrial vehicle collision.
