The Wisconsin DOT’s I-94 North-South Corridor mega project included the replacement of the two-span bridge crossing I-94 on Rawson Avenue. Both I-94 and Rawson Avenue have high traffic volumes, necessitating the use of accelerated construction for the 2013 bridge replacement. Project goals were to reduce impact to I-94 to just one 12-hour closure and to reduce the Rawson Avenue closure from six months to three weeks. The new bridge’s interior support was built of precast caps and columns, and its two 138-ft-wide superstructure spans were installed using self-propelled modular transporters. This presentation will describe the technical aspects of constructing the bridge using precast elements and systems, including lessons learned in the project.
