DAAR provided structure design services on three bridge overlays on I-90, one bridge overlay on an I-90 overpass, and one deck replacement on an I-90 overpass in La Crosse County, WI. The roadway design was performed by the Wisconsin Department of Transportation (WisDOT) Southwest Region. Close coordination with the region was required to ensure consistency in the project plans and construction documents.
As part of a joint venture (SE Design Works), DAAR prepared final structure plans for eight, single-span prestressed girder structures along I-94 and three, three-span prestressed girder structures at the WIS 11 Interchange in Racine County, WI. Also included was the design of two cantilever sign structures.
Design services are being provided for the 10.5-mile rehabilitation of US 12 between Lake Geneva (WIS 50) and Elkhorn (WIS 67) in Walworth County, WI. In addition to the mainline resurfacing on US 12, the project will include work on numerous structures ranging from complete replacements to painting.
