The intersection of Highways 101 and 25 in southern Gilroy will be dramatically improved, taking care of a traffic snafu on the way to Hollister from the San Francisco Bay Area. The NCBS Good Old Fashioned Bluegrass Festival is held each August in Tres Pinos, 7 miles south of Hollister on Highway 25.
The project will be done in phases over a decade with Phase One starting in approximately Fall 2024. The initial work will significantly improve the interchange’s traffic flow to and from the festival location. Later work will further expand highway capacity on both 101 and 25 and will extend Highway 25 to the west. Many sections on the route to the festival have already been upgraded.
The current two-lane bridge over 101 was considered a temporary safety measure when in was built in 1988. Its purpose was to prevent southbound left turns from 101 to 25 across northbound traffic but is now overwhelmed by current traffic volume.
