November 8, 2024 – Vallejo, CA
WMH Corporation (WMH) was honored to be part of the State Route 37 / Fairgrounds Drive Interchange Improvement Project groundbreaking ceremony on Friday, November 8, 2024.
Carl Gibson, PE, the WMH Corporation project manager who led the design of this important infrastructure improvement, was in attendance to join with the stakeholder agencies to celebrate this important achievement for the City of Vallejo and surrounding communities. Stakeholders include Solano Transportation Authority (STA), City of Vallejo, Caltrans, and Solano County.
WMH completed the design in 2023, and the construction is scheduled for completion in early 2026. Carl Gibson noted: “Achieving this milestone takes many years of hard work from all involved, and our engineers are thrilled to see their designs come to life. Congrats on your excellent work!”
Over the next year, the $30-million project will widen and improve 1.5 miles of Fairgrounds Drive and implement a Diverging Diamond Interchange design – the second such configuration in the state and first in the Bay Area – which will significantly improve safety, reduce traffic congestion, as well as vehicle miles traveled and greenhouse gas emissions. The project will make it safer and easier for motorists, pedestrians, transit, and cyclists to access Six Flags and the surrounding Project area. Overall, diverging diamond interchanges require less space than a traditional diamond or cloverleaf interchange and can cost up to 75% less, saving taxpayer dollars, according to the Federal Highway Administration.
The Project also supports Solano 360, a larger countywide economic development to revitalize the area and encourage economic growth and development. This includes a mobility hub at the Fairgrounds site, which is funded by One Bay Area Grant Cycle 3 and various grants provided by the STA to the County — the project sponsor.
WMH is proud to be a major contributor to significant regional transportation projects that improve safety, connectivity, and transportation for all modalities in communities throughout California.
