Grade Separation and Access Project

The in-progress Grade Separation and Access Project represents a step toward completing the Master Plan. This is accomplished by several elements:

• Construction of a new ramp connecting W Evelyn Ave and Shoreline Blvd to provide an alternate route for vehicles
• Closure to vehicles of the at-grade (i.e. street level) crossing of Castro Street across the Caltrain tracks
• Construction of undercrossings and vertical circulation (meaning stairs, ramps, and/or elevators) to allow pedestrians and cyclists to cross from the north side of Central Expressway and the Moffett Boulevard community to the Transit Center and Downtown Mountain View
• An enhanced bicycle connection along W Evelyn between the Shoreline Trail, the Transit Center, and the Stevens Creek Trail
• Designation of areas for bus/shuttle pick-up and drop-off on the south side of Central Expressway next to the transit center and the east side of Moffett Boulevard next to the Adobe Building
• Extension of the Caltrain boarding platforms and replacement of the two at-grade crossings of the tracks between platforms with undercrossings
• Addition of secure bicycle parking at the Transit Center

A fact sheet, describing the stages and components of the Grade Separation and Access Project may be found here. To see information about the public meetings held for the Grade Separation and Access Project, see the Meetings & Workshops tab.

The Grade Separation and Access Project has completed environmental review and preliminary engineering. The final design phase is currently underway, with construction to follow.  See project schedule below. The project is being funded through Santa Clara County’s Measure B program, which is being administered by the VTA. Caltrain will be the lead agency for Final Design and construction of the project.
