Sonoma State Route 116 Capital Preventive Maintenance Project

The Sonoma State Route 116 Capital Preventive Maintenance Project will resurface the existing roadway segment from Church Street in Monte Rio at postmile 7.74 to Mill Station Road near Sebastopol at postmile 25.05, enhancing the structural integrity and safety of this critical transportation corridor in Sonoma County. In addition to pavement rehabilitation, the project includes comprehensive upgrades such as installing or replacing streetlights, renewing guard rails, repairing or replacing culverts, and widening narrow shoulders to accommodate Class II bicycle lanes and bicycle pullouts. Pedestrian infrastructure will be significantly improved with new sidewalks and crosswalks, and all existing facilities will be brought into compliance with current Americans with Disabilities Act standards to ensure accessibility for all users. The project is managed by Caltrans, District 4 – Bay Area/Oakland, with the primary point of contact being Senior Environmental Scientist Christopher Pincetich, reachable via email and phone. Located in Sebastopol, California, the project is currently in the forecast stage with a posted date of July 6, 2026, indicating it is in the early planning phase prior to solicitation. While no solicitation number, set-aside details, or NAICS code are listed at this time, the scope reflects a capital-level preventive maintenance effort focused on modernizing safety, mobility, and accessibility along Route 116 to serve both vehicular and non-motorized transportation needs.
