I-39/90 Rock River Bridges Award

March 22, 2019 By Mysti Nundahl

Westbrook Associated Engineers, Inc. of Spring Green, WI, along with Central Segment Design Team members KL Engineering, Inc. and RA Smith, Inc., was awarded the Wisconsin Department of Transportation’s Excellence in Design Award for Best Consultant Structure Design.  Westbrook served as the structural design engineer for the two new I-39/90 Rock River bridges.

The $1.2 billion I-39/90 Expansion Project extends approximately 45 miles along Interstate 39/90 from the Illinois state line to the US 12/18 interchange near Madison.  The Rock River Bridge project involved reconstructing the existing I-39/90 northbound and southbound bridges over the Rock River from 2-lane structures with 5-foot shoulders to 3-lane structures with 12-foot shoulders, and the ability to expand to 4-lanes with minimal impacts. The new pier and abutment substructure units were designed and constructed to accommodate a future fourth lane on each bridge structure. This key feature added significant long-term value by allowing future widening of the bridges to be accomplished without additional environmental or construction impacts within the river corridor.
