An old sewer line collapsed June 21st on Vine Street at the entrance to the interim roundabout (see image below) – cause unknown. As a result, a by-pass pump was installed on Vine Street and is running across the Chamber of Commerce grounds to Healdsburg Ave. A work zone on the west side of southbound Healdsburg Avenue will impact traffic, resulting in the loss of some on-street parking on the east side of Healdsburg Ave. Duration for this by-pass is unknown at this time. Please proceed through the interim roundabout with extreme caution or find alternate routes.

The Five-Way Intersection at Mill Street/Healdsburg Ave/Vine Street has been converted from an all stop intersection to an interim roundabout. A combination of paving marking, signage and barricades have been installed to direct traffic flow. This will allow all lanes to remain open as construction moves into the next phase of excavation for the box culvert. See rendering below.
Large tractor trailers, RV’s and trucks will not be able to navigate the circle due to size limitations, and are advised to find alternate routes. All other vehicles should drive with caution through the intersection during this transition. Click here for a TRUCK RE-ROUTE MAP.
Healdsburg Avenue Improvements is a multi-faceted engineering and urban design effort to improve the visual, pedestrian and vehicular experience for residents and visitors entering Healdsburg from the Highway 101. The project scope covers four separate, but interconnected projects. The area benefitting from this effort centers on Healdsburg Avenue, starting at Exchange Avenue and continuing north through the existing five-way intersection (Healdsburg Avenue, Mill Street and Vine Street).
Key to this project is improving the five way intersection – pedestrian safety and access, vehicular capacity (largely afternoon traffic turning west onto Mill Street) and resolving complicated signalization requirements of the future SMART train. After studying several alternatives during the CHAP process, a roundabout was deemed to be the most appropriate solution. Based on this conclusion, the CHAP process established a set of Roundabout Guiding Principles to inform the future design and engineering of the roundabout.
