T.Y. Lin International (TYLI), a globally recognized full-service infrastructure consulting firm, announces that the Navy Pier Flyover Lakefront Trail Improvements project has been honored with a 2021 Award of Merit (Highway/Bridge) in Engineering News-Record (ENR) Midwest's Best Projects competition. TYLI was selected by the Chicago Department of Transportation (CDOT) in Chicago, Illinois, to provide professional construction engineering services for the project.
ENR Midwest’s annual Best Projects award program honors the best construction projects and the companies that designed and built them. Opened in stages to provide user benefits as soon as possible, the Navy Pier Flyover Lakefront Trail Improvements separates 25,000 daily users from vehicular traffic and street closings for the Navy Pier entertainment complex.
The Navy Pier Flyover Lakefront Trail Improvements project involved constructing an elevated multiuse path through Chicago’s heavily-congested lakefront and urban area in three phases. The first two phases extended the path from the north end of Jane Addams Park to the north end of the Chicago River Bridge. The third phase, which spans the Chicago River, connects the existing trail on the south side to the new "flyover" pedestrian bridge on the north side.
Construction included a new, steel single-column structure and modifications to existing structures, along with new ramps, approaches, retaining walls, stairs, drainage systems, and Americans with Disabilities (ADA)-compliant connection points. Project scope for TYLI included extensive traffic maintenance, trail detours, and temporary pavements to allow full open trail and roadway access for pedestrians, cyclists, and vehicles.
The Navy Pier Flyover Lakefront Trail Improvements project also included the rehabilitation of the Lake Shore Drive bascule bridge over the Chicago River. Work included modifying the existing bridge houses to repair the 1930s-era limestone façade, replacing 1980s-era vintage electrical controls, and widening movable sidewalk segments to keep the trail from conflicting with the bridge houses during bridge openings.
