The extension of Upper Wacker Drive was constructed to provide access to the St. Regis Chicago, a residential building completed in 2020. The project consisted of rehabbing two spans of the Upper Wacker Drive Bridge, including replacing the concrete deck, structural steel modifications, installation of mircopiles to strengthen the foundations and extending the bridge structure two spans to the east.
The extension of Upper Wacker required the addition of two structural steel support bents, steel plate girders and wide flange steel beams. The new roadway deck incorporates raised planter beds, brick pavers and landscape areas, decorative accent lighting, street lighting as well as providing a roadway turn around and valet parking location.
