MENDOCINO CO., 12/22/25 – Parts of state Highway 1 are closed in Mendocino County due to flooding and other storm impacts, Caltrans announced Monday.
A portion of state Highway 1 is closed near Point Arena due to flooding.
The closure is from Lighthouse Road near Point Arena to the Garcia River, just south of Stornetta Drive.
A second closure of Highway 1, north of Westport, is due to a sinkhole. That closure extends from Westport Cemetery to Wages Creek Bridge. The Mendocino Voice has contacted Caltrans and is awaiting additional information.
Drivers should avoid these areas and seek alternate routes.
The closures come as an atmospheric river continues to inundate the region with heavy rain. As a result, the National Weather Service issued a countywide flood warning through 10 a.m. Monday.
The weather service also issued a flood watch from 10 p.m. Monday through 10 p.m. Friday due to another incoming storm.
According to the National Weather Service, the Garcia River at Eureka Hill Road measured 14.14 feet as of 8 a.m. Monday. No flood stage has been established for the river.
An estimated time for reopening was not available.
Additionally, portions of state Highway 128 and Highway 175 are also closed due to flooding.
