Updated May 6 with road projects throughout Sonoma County.

Watch for road closures and detours in Petaluma as work heats up on the Highway 101 widening project. Here’s the latest information about it and other road construction projects throughout the North Coast during the week of May 5-10.

Petaluma

State Route 116 will be closed Tuesday through Friday while portions of the southbound U.S. 101 bridge are demolished. Hours are 10 p.m. to 5 a.m. Tuesday through Thursday nights and 10 p.m. to 6 a.m. Friday night. Traffic will be detoured to Caulfield Lane and South McDowell Boulevard.

As construction begins on the Old Redwood Highway Interchange Improvement project, northbound and southbound lanes on U.S. 101 will be closed from 10 p.m.-6 a.m. Northbound off and on-ramps will be closed Monday night while the roadway is restriped. Similar work will cause the southbound on and off-ramps to close Tuesday night.

The second part of the city’s Petaluma Boulevard South “Road Diet” work begins on Monday, May 6, with construction crews scheduled to install new traffic signal poles at Western and B streets. It’s part of a project that will reduce the number of lanes from four to two and add a middle turn lane between East Washington Street and D Street. City sources predict the project will take six weeks to complete, and warn drivers to expect occasional lane closures.

Santa Rosa

City crews continue working on water main construction surrounding Montgomery Village. Expect delays this week along Midway Drive between Farmers Lane and Hahman Drive, performed during daytime hours Monday through Thursday. (No construction work will be done on Friday to allow Mother’s Day shoppers to have full access to Montgomery Village stores.)

Crews also have closed the westbound lanes of Sonoma Avenue near Montgomery Village, funneling traffic into one lane each way.

Water main construction will take approximately two weeks and sewer main construction in this same area will directly follow. Streets impacted by the work include Midway, Magowan and Hahman drives, as well as Sonoma Avenue. See a map of the project and updates HERE.

Sonoma County

A crack seal crew will begin Tuesday and Wednesday on Bloomfield Road from Hwy. 116 west of Sebastopol to the end of the improved road section just beyond Tiller Lane, a private road. The length of the section is 1.3 miles. On Thursday the crew will move to Llano Road to fill cracks between Hwy. 12 and Todd Road, 2.27 miles. One lane traffic controls will be in place while crews are working these sections, beginning at 7:30 a.m. daily to 4 p.m.

Two other roads being prepped for chip seals this week include High School Road between Occidental and Sebastopol and Adobe Canyon Road in Kenwood. The Cotati crew will be grinding damaged asphalt and re-paving on High School Road near Analy High School, and Sonoma staff will be grinding and paving along Adobe Canyon from Hwy. 12 to the Sugarloaf Ridge State Park entrance. One lane traffic controls will be in effect daily on these routes.

The Bridge crew will continue work on Geysers Road this week building a retaining wall, and also a second crew will be on Dry Creek Road replacing the first of three failed culverts. The first culvert beginning today is located near the Wilson Winery on Dry Creek Road, followed by two others near the Coffaro Winery. Minor traffic delays are expected with one lane traffic controls.

Lastly, CDF crews are scheduled to assist with roadside brush removal if available on Tuesday and Wednesday. Both Delta Camp in Suisun and Konocti Camp in Lake County have sent strike teams to fight fires this past week. Brush removal is scheduled for Barnett Valley Road and Martinelli Road this week.
