T.Y. Lin International (TYLI) is providing professional construction engineering services for Navy Pier Flyover Lakefront Trail Improvements for the Chicago Department of Transportation.
This long-awaited improvement separates 25,000 daily lakefront trail users from turning vehicular traffic and street closings for the Navy Pier entertainment complex on Chicago’s Lake Michigan shoreline.
The trail will be constructed in three phases, with the first two phases extending from the north end of Jane Addams Park to the north end of the Chicago River Bridge. The third phase, which will span the Chicago River, connects the existing trail on the south side to the new “flyover” path on the north side.
- The project involves constructing an elevated multiuse path through a heavily-congested lakefront and urban area.
- Construction includes a new, steel single-column structure, modifications to existing structures, and new ramps, approaches, retaining walls, stairs, drainage systems, and Americans with Disabilities (ADA)-compliant connection points.
- Path improvements will incorporate aesthetic landscaping and architectural elements.
- TYLI is overseeing the removal and disposal of any special or radioactive waste in areas identified as having the potential for contamination.
- The project included extensive traffic maintenance, trail detours, and temporary pavements to allow full and complete open trail and roadway access for pedestrians, cyclists, and vehicles.
The Navy Pier Flyover Lakefront Trail will rise from the north end of Chicago’s Jane Addams Park onto the new single-column structure running through the park and adjacent to Lake Shore Drive/US41. Winding over the Grand Avenue intersection, the elevated path will attach to upper Lake Shore Drive, cantilevering off the east side of an existing structure. The path will then cross over Illinois Street and intersect with the newly-constructed Navy Pier ramp near the Ogden Slip. From this point, the trail will run adjacent to the middle level of Lake Shore Drive through DuSable Park, with the final phase crossing the Chicago River and connecting to the existing trail on the south end.
