Construction Considerations
25 Churchill Avenue – Partial Underpass with and without Landscape Strip • Bike/ped crossing built first to maintain access high school • Method TBD – Proceeding by assuming box jacking and no shoofly • Utility relocation, including potential undergrounding of electrical • Phasing for maintenance of traffic, retaining walls & bridge construction • Alma Street may be reduced to one lane during construction • Soil export from site
Community Feedback
26 Churchill Avenue – Partial Underpass with and without Landscape Strip • Prioritize student access and safety.
• Include a physical buffer for walkability and perceived safety along Alma Street. • Calm Alma Street traffic while preserving practical neighborhood access and egress. • Provide clarity of potential property impacts including driveway, sidewalk, and planter strip changes.

Below are preliminary construction only
cost estimates developed in 2020 and
updated in 2024 as part of the City’s previous
planning efforts.
• Churchill Avenue – Partial Underpass
with Bike/Ped Crossing
• $260M to $320M combined
• Meadow and Charleston Hybrids
• $390M to $480M combined
• Meadow and Charleston Underpasses
• $690M to $850M combined
Previous Preliminary Cost Estimates
62 Key Considerations:
• These preliminary costs have not been vetted or
validated by the integrated project team.
• Recent commercial industry contractor cost
estimates for grade separations on the Caltrain
corridor have shown total project costs are
substantially higher than previously estimated
by project sponsors.
• Total (Delivery + Construction) engineering
cost estimates for project completion will be
complete in mid-2026 based on 15% Design
Drawings, to be informed by:
• Construction work hours/rail service disruptions
• Construction clearances required for active
electrified rail operations
• Current market costs
