Project funding

In 2018, San Benito County voters approved Measure Ga one cent sales tax for improving transportation throughout the entire region. The approved measure commits up to 50% of the tax revenues to Highway 25. 

Measure G established an Oversight Committee to oversee the use of measure funds. The Oversight Committee is composed of residents that represent the geographical, social, cultural, and economic diversity of the community.
