SONOMA COUNTY - Caltrans will pave State Route 116 between Lakeville Highway and Old Adobe Road just east of Petaluma, a two-and-a-half-mile stretch of rural highway also known as Stage Gulch Road. 

Ghilotti Brothers of San Rafael is the contractor for the $1million project to pave the two-lane highway. Caltrans will work an expedited schedule, starting Monday, April 19, 2021 and completing work in early May.

Caltrans will fully close the road on Monday and Tuesday during the project’s first week and Monday – Friday during the second week. (See schedule below.) 

Residents and delivery vehicles destined to locations within the paving limits will be flagged through the closure points. Other traffic will be directed to a clearly signed detour around the project limits.

Detours: Westbound Traffic - Lakeville Highway to Frates Road to Adobe Road  Eastbound Traffic - Adobe Road to Frates Road to Lakeville Highway 

During the third week of the project, Caltrans will implement one-way traffic control. Motorists should expect delays or take the detour route to save time. 

As part of the roadway rehabilitation, Caltrans will grind off the old pavement and replace it with a fresh layer of asphalt.
