T.Y. Lin International (TYLI), a globally recognized full-service infrastructure consulting firm, announces that the Dublin Link in Dublin, Ohio, has been selected as the 2020 Outstanding Project Winner (New Bridges or Transportation Structures) in the National Council of Structural Engineers Associations' (NCSEA) annual Excellence in Structural Engineering Awards competition. TYLI served as Prime Consultant for the final bridge design, working closely with the City of Dublin to develop the unique bridge concept, which resulted from a collaboration between TYLI and the architect, Endrestudio of Emeryville, California. The landmark pedestrian bridge is a critical transportation link for pedestrians and cyclists crossing the Scioto River and central to the vibrant, walkable, mixed-use district being developed around the City's civic and historic core.
The annual NCSEA Excellence in Structural Engineering Awards competition honors structural engineering ingenuity throughout the world. Projects are judged on innovative design, engineering achievement, and creativity.
The 760-foot-long Dublin Link was not only designed to provide a safe, efficient crossing for its users, but it was also engineered to provide a dramatic experience. The bridge follows a sinuous "S" curve alignment, with a steel superstructure that passes through the "eye" of the concrete pylon tower without any vertical support. The deck is a steel box girder with an asymmetric "V" form, which changes shape as users cross while maintaining a 14-foot clear deck width from end to end.
The focal point of the bridge is the 176-foot-tall pylon, which measures 110 feet high from the walking surface to the top of the tower. The bridge profile features one main suspension cable, with a single plane of hanger cables attached along only the inside edge of the curved bridge deck. Dynamic programmable lighting allows the City to change the bridge's color scheme at night to present different themes.
After completing the final design, TYLI worked to develop the project schedule and produced a plans, specifications, and estimates (PS&E) package and solicited bids. The firm worked with numerous structural, civil, and electrical engineering firms based primarily in Ohio to maintain local consultant participation. A construction manager-general contractor delivery method was selected by the City for this project - a first in Ohio.
"On behalf of T.Y. Lin International, the City of Dublin, and the entire project team, we are very pleased that the National Council of Structural Engineers Associations has honored the Dublin Link as the 2020 Outstanding Project winner in the New Bridges or Transportation Structures category," said Dan Fitzwilliam, P.E., TYLI Senior Bridge Engineer.
