T.Y. Lin International (TYLI) served as Prime Consultant responsible for providing construction engineering, with significant structural and civil design support during construction, for the North Atwater Non-motorized Multimodal Bridge over the Los Angeles River in Los Angeles, California.

The 325-foot-long structure features a dramatic, 125‑foot‑high mast and steel suspension cables. A symbol of achievement for the Los Angeles River Revitalization Plan, the signature bridge connects the rapidly-growing Atwater Village on the east bank to the Los Angeles River Bike Path on the west bank and provides access to the extensive Griffith Park trail network.

To accommodate pedestrians, cyclists, and equestrians, the bridge deck is divided into two separate 12-foot‑wide pathways. The pedestrian/bicycle path uses a hardwood deck and stainless-steel mesh railings, while the equestrian side is topped with horse-friendly rubber paves and a less transparent wooden picket railing system.

When TYLI joined the ongoing project as Engineer of Record, existing project plans required significant review, numerous construction details, and the evaluation of critical elements, including the foundation, center pylon, and environmental footprint. TYLI bridge designers responded by providing sound, buildable construction plans without disrupting the contractor’s schedule.

Project Highlights:

  • TYLI successfully helped to control costs while coordinating field challenges and design modifications.
  • The cable stays along the length of the structure allow for a very lightweight bridge superstructure.
  • The thin profile of the superstructure allows the abutments to remain as low as possible to minimize impacts to the approaches.
  • TYLI designed a system of tuned mass dampers to reduce the magnitude of vibrations during severe equestrian loading to an acceptable range and prevent vibrations from continuing after horses pass off the bridge.
  • The crossing is potentially the first cable-stayed equestrian bridge in the world.
