Council Approves Concept Design for Adobe Creek Overcrossing

The Adobe Creek/Highway 101 Pedestrian Overcrossing project is one step closer to reality after the City Council voted 9-0 in favor of moving forward with the latest design concept at its meeting on Nov. 7. 

Council approved the baseline concept design presented by Biggs Cardosa and Associates (BCA) for a 12-foot wide bridge that is expected to provide year-round use, be a bird-friendly structure, and meet the project’s $14 million budget. By contrast, the Lefkowitz Tunnel under Highway 101 that is currently used is open on average only half the year due to seasonal flooding.

The bridge would span over Highway 101 and would be used by bikers and pedestrians to get from south Palo Alto to the Baylands recreation area, and businesses on both sides of the highway, including Google. Google has offered to contribute $1 million toward the bridge.

The 12-foot baseline bridge design consists of:

  • a bowstring steel truss principal span
  • concrete approaches
  • an eastern approach overlook platform
  • western approach alternative access (originally anticipated to be a stairway)
  • enhanced lighting
  • Adobe Creek Reach Trail head improvements
  • educational signage

Council was also presented with several enhancement options that would increase the cost up to $3.5 million. The enhancements include a 16-foot wide version of the bridge, five alternative structure designs, separated bike and pedestrian areas, enhanced railings and fencing, and other amenities. Council could revisit these enhancements at a later time if additional funding is secured. At this time however, they approved $130,000 in amenities from the Google contribution fund to pay for items such as water drinking stations, enhanced benches and bike racks.

Funding for the bridge is currently coming from a variety of sources including a grant from the Santa Clara County Recreation Trails program, as well as an anticipated One Bay Area Grant (OBAG).  

The City anticipates 74,000 people will use the bridge once completed. Under the current timeline, construction is slated to begin in 2019 and is expected to be completed in spring 2020.
