State Route 37/Fairgrounds Drive Interchange Project Media Bar

The Solano Transportation Authority (STA), in partnership with the City of Vallejo, Caltrans, and Solano County, is leading construction on the State Route 37/Fairgrounds Drive Interchange Improvements Project.

This initiative aims to create an efficient route to and from State Route-37 in Vallejo by implementing an innovative Diverging Diamond Interchange design. Not only will this interchange improve traffic flow and safety, but once completed, it will be the second of its kind in California and the first in the Bay Area. This interchange will also boast unique features that makes it safe for not just motorists, but also safer and easier for pedestrians and cyclists to access and navigate.
