Mount Hamilton Road (CA Hwy 130) is closed between Three Springs Road and Quimby Road for road repairs, and will remain closed until repairs are completed (November 2023). Visitors driving from San Jose will need to take Quimby Road, which is narrower and steeper than Mount Hamilton Road. Please drive carefully.
