Today, a fresh landslide squeezed traffic down on State Route 116 at Laurel Dell Avenue near Monte Rio, blocking the westbound lane and turning the already tight, winding corridor into a slow crawl.
The slide dumped debris across the highway on the stretch that links Guerneville to coastal Highway 1, triggering travel alerts for drivers up and down the lower Russian River. Crews moved in to assess the slope and clear the mess while officials warned motorists to brace for delays and follow instructions from workers on scene.
What officials posted
The first public word came in a short social media alert from Caltrans District 4, which reported the westbound lane as blocked at Laurel Dell Avenue. That early Sunday post quickly translated into traveler alerts for the lower Russian River corridor, where drivers are used to learning the hard way when something goes wrong on 116.
For live lane closures and any detours that might pop up, the region’s official traveler information is available at 511.org.
A familiar trouble spot
This section of SR 116 has been repeatedly hammered by winter storms and river erosion. In January, a serious washout near Monte Rio reduced the highway to a single lane for an extended stretch and kicked off months of repair work. Coverage from SFist at the time highlighted the emergency shoring and long-term stabilization efforts already underway.
What drivers should know
For now, drivers should plan on slow going as crews secure the slope and clear debris. Before heading out, check Caltrans QuickMap or 511.org for real-time updates on lane status and any detour guidance.
Caltrans District 4 has an active retaining wall and slide repair program in the Monte Rio area aimed at stabilizing slopes and protecting this vulnerable stretch of highway, according to the agency’s updates on its project page.
This story will be updated as officials release new information on repairs or traffic controls. Until then, drivers are urged to pad their travel time, watch for flaggers and temporary signals, and take it slow through the slide zone.
