The Don Burnett Bicycle-Pedestrian Bridge, renamed from Mary Avenue Bridge on July 19, 2011, [4] [5] is a cable-stayed bridge over Interstate 280 (California), spanning Cupertino, California and Sunnyvale, California, used for bicycle and pedestrian traffic. It is the only cable-stayed pedestrian bridge over a highway in California. [6] At night, the bridge is lit up and can be seen by those driving on Interstate 280. The project was awarded a Helen Putnam Award of Excellence. [7] [8] It also won the California Transportation Foundation's Pedestrian/Bicycle Project of the Year. [9] [10]
The bridge was completed in 2008 and it cost $14.8 million. [11] Roughly 80 percent of the funding for the bridge came from grants, bonds and the Santa Clara Valley Transportation Authority. [12] The original plan for the bridge was to use concrete to keep costs down, but a steel design was chosen after the bids for a concrete bridge came in too high. [11]
North of I-280, Mary Avenue ends in a parking lot and drop-off area for Homestead High School. Mary Avenue continues south of the highway and ends at De Anza College's north entrance.
The address for the southern entrance to the bridge is 10655 Mary Ave, Cupertino, CA 95014-1355. The address for the northern entrance to the bridge is 21370 Homestead Rd, Cupertino, CA 95014.

Bridging State Route 84 across the bay, it has three lanes each way and a separated bike/pedestrian lane along its south side. Like the San Mateo Bridge to the north, power lines parallel the bridge.

A footbridge is a bridge designed solely for pedestrians. While the primary meaning for a bridge is a structure which links "two points at a height above the ground", a footbridge can also be a lower structure, such as a boardwalk, that enables pedestrians to cross wet, fragile, or marshy land. Bridges range from stepping stones–possibly the earliest man-made structure to "bridge" water–to elaborate steel structures. Another early bridge would have been simply a fallen tree. In some cases a footbridge can be both functional and artistic.

People in the San Francisco Bay Area rely on a complex multimodal transportation infrastructure consisting of roads, bridges, highways, rail, tunnels, airports, seaports, and bike and pedestrian paths. The development, maintenance, and operation of these different modes of transportation are overseen by various agencies, including the California Department of Transportation (Caltrans), the Association of Bay Area Governments, San Francisco Municipal Transportation Agency, and the Metropolitan Transportation Commission. These and other organizations collectively manage several interstate highways and state routes, eight passenger rail networks, eight trans-bay bridges, transbay ferry service, local and transbay bus service, three international airports, and an extensive network of roads, tunnels, and bike paths.
Interstate 80 (I-80) is a transcontinental Interstate Highway in the United States, stretching from San Francisco, California, to Teaneck, New Jersey. The segment of I-80 in California runs east from San Francisco across the San Francisco–Oakland Bay Bridge to Oakland, where it turns north and crosses the Carquinez Bridge before turning back northeast through the Sacramento Valley. I-80 then traverses the Sierra Nevada, cresting at Donner Summit, before crossing into the state of Nevada within the Truckee River Canyon. The speed limit is at most 65 mph (105 km/h) along the entire route instead of the state's maximum of 70 mph (110 km/h) as most of the route is in either urban areas or mountainous terrain. I-80 has portions designated as the Eastshore Freeway and Alan S. Hart Freeway.
