Cost, Funding, and Schedule
The estimated total cost of Phases 1 and 2 is $275 million. Phase 1 is now fully funded. Phase 1 Design and Environmental Reevaluation will be complete by Summer 2026 with Phase 1 Construction beginning in Fall 2026. Phase 2 Environmental Reevaluation began Fall of 2025. Caltrans is prioritizing the estimated $138M needed to fully fund Phase 2 Right of Way and Construction by working with our local and regional partners. Phase 2 Design can proceed without these funds. However, the remaining schedule is dependent upon future funding in full for both Phase 2 Right of Way and Construction.
