Caltrans implements one-way traffic control

Sonoma County – Weeks of heavy rain and a swiftly flowing Russian River have caused the earth to give way along the eastbound shoulder of Route 116 between Duncan Road and Monte Cristo Avenue just west of Monte Rio in Sonoma County.

Cars on State route 116 where a landslide occurred on State Route 116 west of Monte Rio in Sonoma County.

The slide happened at about 4:00 PM, Monday, taking out guardrail and trees, undermining a 40-foot section of the eastbound shoulder.

Caltrans maintenance crews have put the road under one-way traffic control as project managers work to secure funding and engineers consider design options to repair the subsiding road.

It is likely that repairs would involve two stages, one to temporarily bolster the road and another to make long-lasting repairs.

In the meantime, the damaged road will likely remain under one-way traffic control.
