The South Bayfront Pedestrian Bridge project involves the design and construction of a pedestrian-bicycle bridge which will connect to the Emeryville Greenway on the east side and will provide a path across the railroad tracks to connect to the Bay Trail to the west. It will also provide convenient access from central Emeryville to the Bay Street Center. The project includes the ramps and connections from the bridge to existing or proposed projects. On the west side, it will connect to Ohlone Way and the Bay Street parking garage. On the east side, it connects to the future Horton Landing Park.

The main span consists of an S-curved single span across the railroad tracks, about 230 feet long, supported at its ends by concrete bents. It is supported by a single straight bowstring truss/arch that extends diagonally across the deck; the top chord/arch rib is a pair of steel tubes, the bottom chord/tension tie is within the deck framing, and the cable diagonals/suspenders support the deck edges. A concrete slab traveled way, with fencing and lighting, is carried by the steel deck framing.

Over the last two months the structural arch and frame of the bridge was assembled in the future Horton Landing Park. Over the December 18-20 weekend, the structural frame of the bridge was lifted into place. Here is a time lapse video of the move:


Bridge History

  • The Bridge has been in the Emeryville General Plan since the 1980’s with the plan to provide a safe pedestrian-bicycle connection linking the east and west sides of the City over the railroad tracks.
  • Project Development started in 2002 as the Emeryville Redevelopment Agency Project – Architectural Design
  • Environmental Review in 2008
  • Engineering Design started in 2009
  • Project halted with the California Deauthorization of Redevelopment Agencies
  • City sued California for project funds -$12,000,000; returned in 2014
  • Project reactivated in 2015
  • Right of Way negotiations completed from 2015 through early 2019
  • Contractor Pre-Qualification Process in early 2018
  • Construction Contract bid and awarded in mid 2019
  • Construction commenced in January 2020 and anticipated to be complete by Fall 2021

Bridge Fabrication Details

  • The signature feature of the project, the arch span, is comprised of materials and components fabricated in three continents and 6 states.
  • Cables were fabricated in Switzerland and cable sockets were fabricated in Houston, Texas. The cables were fully assembled in Montreal, Canada.
  • Bridge fabrication was performed in Arizona and initial assembly completed there at the end of October.
  • The bridge deck and arch components were shipped by truck to Horton Landing Park in early November.
  • Assembly of the bridge arch structure was completed in mid-December. Deck and arch components were welded and bolted together, and temporary towers were used to ensure the appropriate geometries to conform to the design.

Bridge Lift

Due to constraints of working over an active railway corridor the bridge was assembled outside of the Union Pacific Right of Way and lifted into place over the tracks. The bridge lift is a delicate operation and requires significant preparation to prepare and perform the lift. Operation to complete this activity culminated in a 3-day continuous effort working 24 hours a day to ensure a safe and efficient operation with minimal impact to train operations.

The bridge lift required months of preparation:

  • Realignment of some utilities and site preparation were initially performed.
  • Construction of bridge abutments on both the east and west sides, including driven piles to support the structure, were installed.
  • Preparation for the lift required placement of crane mats and steel plates to support the cranes and provide an even surface for the cranes to travel on to move the bridge.
  • Erection of the cranes and balancing of the bridge load was performed.
  • UPRR restricted train traffic for an approximate 4-hour window on the night of Saturday, December 19 to allow the construction team access to the railroad right of way.
  • The bridge was lifted and moved into place during the first 1.5 hours of the window and structurally secured immediately thereafter with crane support. The cranes and cranes mats and plates were then removed from the UPRR track area, and train traffic was restored to service prior to early morning on Sunday, December 20.


The advancement of this project has continued through the COVID-19 Pandemic shelter-in-place order. The City and the Contractor are working together to conform to the latest Health Orders issued by Alameda County and the State of California to minimize infection risks to workers, residents, and the general public.

The pandemic has impacted the project in supply chain delays. The contractor and the City have worked together to minimize delays through schedule and sequence of work modifications.

Park Improvements

The new Horton Landing Park will be built on the east side of the train tracks. It will be a new addition to the Emeryville Greenway. Pathways in the park will connect the bridge to Horton Street at two locations: south of 53rd St and near Stanford Ave. The Greenway within Horton Landing Park will connect to a future greenway segment that extends southward to Sherwin near Halleck Street.

On behalf of the City Council, City Manager and City Staff, we wish to acknowledge and thank the community of Emeryville for your support and accommodation of this complex construction. The support and partnership of BayStreet (Madison-Marquette) and Novartis has been key to accommodating access to perform the work necessary to deliver this project. Thanks to the dozens of technical and construction consultants who have worked for years to design and bring to life this signature structure in Emeryville. We look forward to the grand opening of this facility in Fall 2021!
