Construction is now underway on a major rebuild of the Wolfe Road bridge over I-280, a project which should improve safety and accessibility for people walking and biking on a very busy freeway interchange near Apple Park. The $124 million effort is led by the Santa Clara Valley Transportation Authority (SC VTA) in partnership with the City of Cupertino and Caltrans. It replaces the existing overpass with new pedestrian infrastructure, Class I and Class 2 bike lanes, redesigned crossings at off ramps, and additional car lanes. Road and bike lane construction is expected to take until 2029, with periodic lane and ramp closures likely during that time. The following two years will then have landscaping work on the changed areas.
Residents are being kept updated on traffic impacts. For example, I receive weekly updates on construction impacts and road closures via email so I can plan to avoid the area when it looks like traffic will be affected by construction. See below for how to sign up for those updates in your mailbox, too.
Changes for cyclists and pedestrians on the bridge
For years, cyclists and pedestrians crossing I-280 at Wolfe Road have had to cross high-speed ‘slip’ lanes onto the freeway and use a narrow single-line bike lane while walking and biking next to heavy traffic. Most cyclists (like me) avoid this bridge at all times as it is so dangerous, preferring to go ½ mile each way out of the way to use the Blaney or Tantau bridges. HMH, the design firm, has substantially improved the current design, adding separated bike lanes and pedestrian lanes, wider sidewalks, landscaped buffers, and signalized crossings at freeway ramps. The interchange will also include sensors embedded near crossings to detect approaching cyclists and trigger red lights for vehicles, and pedestrians will get push-button crossings. In a 2023 interview about the project, John Cacciotti, project manager for HMH, described the goal for the project to accommodate “all ages and abilities” for cyclists and pedestrians.
Connectivity to the Tamien Innu
Another major improvement will be a direct connection to the planned Tamien Innu (I-280 Trail). Right now, the trail has only the eastern segment moving forward (Vallco Parkway to Wolfe Road) and it’s unfortunately been in design for years with no sign of construction. The bridge is planned to tie into the trail there on the bridge’s eastern side between the Hyatt House parking lot and the I-280 sound wall. When and if the other segments ever get completed, this will form a great east/west off-street connection in Cupertino. This will further the “multimodal” approach (like Complete Streets projects) the overpass project appears to have which supports walking, biking, transit, and driving together, with all modes of transportation being accommodated.
Resident Concerns
Not everyone is happy with the project, though. Some residents and community members argue the project still prioritizes additional vehicle lanes over transit investments because it increases the number of lanes. Increasing lanes has not been shown to meaningfully reduce congestion. Other issues are concerns about increased noise for the homeowners living on Mine Court, south of Homestead and adjacent to the freeway. Trees are being removed due to the on-ramp changes, which likely will increase noise and visibility for these residents.
The I-280/Wolfe Road interchange and bridge reconstruction project in Cupertino is expected to cost a total of $124M, funded through a combination of regional transportation tax revenue, local government contributions, state funding, and private support ($4M) from Apple.
