Update on the Design Options for the I-280 Interchange at Wolfe Road. Excerpt from the Staff Report and Links to the Designs
Reviewed at the Cupertino City Council were designs for the future I-280 Interchange that were intended to be funded by private developers such as Apple, The Hamptons, and Vallco to redo this last outdated cloverleaf interchange. The Hills at Vallco project pledged $30 Million to fund this project that will now be paid by tax payer dollars to be completed.

From the Staff Report:
"HMH was retained by Santa Clara Valley Transportation Authority (VTA), in
partnership with the City of Cupertino (City), to complete a Project Alternative Analysis and preliminary engineering work, through a Project Initiation Document (PID), of possible concepts to relieve projected traffic congestion and improve bicycle and pedestrian connectivity at the I-280 / Wolfe Road Interchange. The I-280 / Wolfe Road Interchange serves as a major access point to the City. Immediately adjacent to several large developments, most notably Apple Campus 2, vehicular, transit, bicycle and pedestrian volumes are expected to increase significantly before the project design horizon of 2040. The goals of VTA and the City, as partners on the I-280 / Wolfe Road
Interchange Improvements Project (Project), are to investigate alternatives and initiate project development for a cost effective solution to improve traffic efficiency and safely accommodate bicycles and pedestrians while efficiently using existing right-of-way.
The existing interchange is outdated for the highly intensified land uses in the vicinity of the Project. The Wolfe Road Interchange Project offers an opportunity to develop a landmark facility that complements the land uses on either side of the I-280 freeway, improves access and circulation for the intense mix of residents and workers expected in the area, and will create a model multimodal facility, accommodating autos, transit, bikes and pedestrians with landscape and architectural design features that enhance the experience for all users."
