Caltrans and Sonoma County this month will start road improvement projects at either end of Arnold Drive in the Sonoma Valley.
Sonoma County’s project will repave about a mile of the north end of Arnold Drive from Glen Ellen to Highway 12. At the southern end, Caltrans will be working on improvements to the Arnold Drive/Bonneau Road intersection, which at that point is signed Highway 116 and Highway 121.
Caltrans and the Sonoma County Transportation Authority will have a community meeting on its project this Wednesday. The purpose of the project, Caltrans says, is to relieve congestion and enhance mobility for pedestrians and bicyclists. The public open house will provide an opportunity to learn about and comment on the project’s purpose and need, alternatives that have been conceptually identified, and potential environmental effects, Caltrans said. The meeting will be 6:30 p.m. to 8:30 p.m., Wednesday, Nov. 5th, at Schell-Vista Fire Station, 22950 Broadway, Sonoma.
The county released details of its project:
In late November, you will see notices of road construction for 0.91 miles of Arnold Drive from the north end of the bridge over Sonoma Creek in Glen Ellen to the Highway 12 intersection. This is part of the ongoing Pavement Preservation Program approved and funded by the County Board of Supervisors. A conventional approach will be followed which involves removing and replacing deteriorated areas of pavement, called “digouts” and you may see “alligator” cracking, rutting, or other surface imperfections. Once the base materials are repaired, the roadway will be overlaid with a topping of asphalt.
Expect traffic delays while the repairs are made and during the actual paving operation. Local access will be provided. Bicycle travel through the corridor is not recommended until the final asphalt overlay is applied. The finished product will essentially be a new road that should give many years of good service before any additional significant pavement work will be needed.
This work is dependent on weather conditions and temperature. The contractor is Ghilotti Construction; they will give periodic updates on their schedule. Traffic will be disrupted particularly during the grinding and mixing operation. The hours of operation will be between 8 a.m. and 7 p.m.
Once the construction begins, you can contact Ghilotti Construction at 707-585-1221 or the County of Sonoma Public Works Construction Office at 707-565-2231.
