The California Powder Works Bridge is located about 2 miles (3.2 km) north of downtown Santa Cruz, spanning the San Lorenzo River just downstream of Henry Cowell Redwoods State Park.

The bridge carries Keystone Way, a private road in the residential development known as the Paradise Park Masonic Club.

The property was purchased by a Masonic organization from Fresno, and developed as a summer colony they dubbed "Paradise Park".
