LakeFront Trail

The 1,750 ft. long, $60 million “Navy Pier Flyover” is a popular cycling, walking and running venue. With many site constraints and limited clearances, a meander (bend or curve or spine rib or roller coaster) form was essentially the only option for the grade-separated path way. A dramatic steel spine-rib superstructure support achieved the objectives of both form and function. The longitudinal spine-rib support system accommodates the complex bridge’s need to curve both horizontally and vertically and provides the desired aesthetics.
