Bridges to Prosperity McNary Bergeron

PROJECT HIGHLIGHTS: ST. CROIX CROSSING

The St. Croix Crossing will replace the 80 year-old Stillwater Lift Bridge with a new four-lane extradosed bridge to connect expressways on both sides of the St. Croix River. The joint project between MnDOT and WisDOT plans to realign Hwy 36 and Hwy 35, build a three-mile connection to WIS Hwy 64 from the new bridge, and construct WIS Hwy 35 overpass.

Our Role

McNary Bergeron is providing construction engineering services including construction analysis, geometry control, falsework design, and shop drawings. We are also independently checking the lifting equipment used to erect precast concrete segments.
