Storm Damage Causes Multiple Road Closures Across San Luis Obispo County

Recent storms have caused damage across San Luis Obispo County, prompting multiple road closures as emergency crews continue repair and safety work.

A stretch of Monterey Street near the historic Fremont Theater was closed after part of the theater’s sign fell Tuesday morning following the storm.

The sign fell onto Monterey Street and the adjacent sidewalk, scattering debris and prompting officials to shut down the area while crews assessed the damage.

Monterey Street is closed between Santa Rosa and Osos streets. Sidewalks directly in front of and across from the theater are also closed to pedestrians. Access to the Courthouse and County Building remains open.

City officials said the closure will remain in place until the area is deemed safe to reopen.

Additional traffic impacts are reported at the Carrizo Creek Bridge on Highway 166, where one-way traffic control is in place as emergency work continues, according to Caltrans District 5 lane closure updates.

Motorists traveling through the area should expect delays of approximately 10 minutes.

Although weather conditions are improving, the effects of the recent storm remain. The San Luis Obispo County Fire Department warned of possible minor flooding in low-lying neighborhoods and areas with poor drainage.

Officials cautioned that steep terrain may be vulnerable to rockslides and mudslides. Saturated soil conditions can increase the likelihood of hillside movement in some areas.

☀️ The sun may be out, but SLO County creeks, rivers & streams are still moving fast from recent storms.

Officials are urging residents to remain cautious around floodwaters as part of the “Turn Around, Don’t Drown” safety campaign. They noted that as little as six inches of moving water can knock a person down, while 12 to 18 inches can carry away most vehicles.

Creeks, rivers, and streams throughout the county remain fast-moving due to the recent rainfall, even as weather conditions are improving.
