DLK was commissioned by the Chicago Department of Transportation to provide architectural and landscape design for the rehabilitation of Wacker Drive, a historic, two-tiered roadway that serves as a major artery for Chicago's business district. Working with the Illinois Historic Preservation Agency, DLK is managing the reattachment of the Drive's historic limestone and granite façade to a new viaduct structure, and creating a pedestrian ramp to replace the existing vehicular ramp.

DLK is also designing the streetscape for the Drive. New lighting, planters, benches, and sidewalks will complement the rehabilitated historical architecture. A new plaza will contain shade trees, a fountain, a glass-enclosed kiosk, and a monumental Loredo Taft sculpture.
