A deadly crash on eastbound State Route 12 at Kelly Road in Napa this afternoon shut down all eastbound lanes and left traffic crawling through Jameson Canyon as investigators worked the scene. One person was killed in the collision, and authorities have so far released few details about what happened.
At 2:03 p.m., the California Highway Patrol’s Golden Gate communications center logged a collision on eastbound Highway 12 at Kelly Road and indicated that one person had died, according to the CHP. Crews shut down all eastbound lanes and had not yet provided an estimate for when the roadway would reopen, KTVU reported.
Traffic and detours
Drivers were warned to expect major delays while crews cleared the scene and to seek alternate routes to avoid the growing backup. According to 511.org, Bay Area travel alerts showed the closure and pointed motorists to agency updates for real-time information.
What officials say
Authorities have not yet released details about what caused the crash or how many people were involved, KTVU reports. The CHP remained on scene to investigate while tow crews worked to clear the wreckage, and officials had not announced a time for reopening the highway.
Why this stretch matters
State Route 12 through Jameson Canyon is a key connector in southern Napa County and has long been flagged for safety and congestion fixes. Local planners are pursuing improvements at the SR-29/SR-12/Airport Boulevard and SR-12/Kelly Road junctions to cut down on backups and collisions. As part of that effort, the Napa Valley Transportation Authority is advancing an alternatives analysis and environmental review for an interchange at SR-12 and Kelly Road, according to NVTA.
