New Interchange for Rapid Growth
The Whitney Ranch community of Rocklin has experienced rapid growth in both residential and commercial markets. This new interchange and associated improvements provide much-needed access to Whitney High School, William Jessup University, and future developments. The project consisted of extending Whitney Ranch Parkway to State Route (SR) 65 as well as adding a new interchange at SR 65 and Whitney Ranch Parkway (between Sunset Boulevard and Twelve Bridge Drive).
Psomas provided construction management, resident engineering, inspection, construction staking, materials testing oversight, and administration services for the project. Major elements of the project included:
- Four-lane overcrossing spanning SR 65 (eventually to be widened to eight lanes)
- Northbound off-ramp
- New on-ramps in both the northbound and southbound direction
