Rengstorff Avenue Grade Separation Project

Rengstorff Rendering 8.14.2020
Project Summary
Caltrain in partnership with the City of Mountain View propose to separate the existing at-grade Caltrain tracks from the roadway crossing at Rengstorff Avenue in the City of Mountain View. This project will help improve public safety for pedestrians, cyclists, vehicles and rail while also improving overall traffic flow and travel reliability along adjacent streets and intersections surrounding the crossing.      

The proposal will lower Rengstroff Avenue and Central Expressway below Caltrain tracks. A new pedestrian overcrossing will be constructed across Rengstorff Avenue to maintain east-west pedestrian and bicycle traffic between Crisanto Avenue and Leland Avenue that would otherwise cross the existing intersection. 

The project is currently in preliminary design phase. This grade separation project is statutorily exempt from California Environmental Quality Act (CEQA). Environmental studies for National Environmental Policy Act (NEPA) clearances are currently underway. 

Schedule

  • Preliminary Design (35%) and Environmental Clearance: Fall 2019 to Winter 2020
  • Final Design and Environmental Permitting: Winter 2020 to Winter 2022 (Targeted)


Public Involvement

Public outreach will be done once adequate engineering design and environmental assessments have been performed. The City of Mountain View will be the primary contact for public information.
