Boyes Boulevard Bridge Ribbon Cutting Ceremony

Boyes Boulevard Bridge Ribbon Cutting Ceremony 


After weeks of anticipation and detours, Ghirardelli Associates, alongside Sonoma County Department of Transportation and Public Works, celebrated the reopening of the Boyes Boulevard Bridge! The ceremonial ribbon cutting took place on Friday, July 16, 2021.

Sonoma County’s Boyes Boulevard Bridge Replacement Project replaced the deteriorating and seismically vulnerable existing two-span, steel girder bridge, which was constructed in 1955 over Sonoma Creek.

The new bridge is a 94’-6” long single-span precast girder bridge, founded on 36” CIDH piles. The project was constructed over two seasons with a winter suspension.

Ghirardelli Associates was selected as the prime consultant to provide full construction management services for the federally funded Sonoma County Boyes Boulevard Bridge Replacement project. Our services included project management, resident engineering and contract administration, civil and structural construction inspection, office engineering, and source inspection.

We are proud to provide support to Sonoma County Department of Transportation and Public Works!
