The project will expand the highway to four lanes to improve safety and reduce traffic. Other planned improvements include an interchange where Highway 25 crosses Highway 156, and more options for public transportation and ridesharing.

Kick-off Environmental Phase
In 2018, San Benito County voters approved Measure G – a 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.
