IH 43 (Rock Freeway), STH 164 Interchange

DAAR prepared final structure plans for two bridges on IH 43 over STH 164 in Waukesha County, WI. The replacement structures were widened in accordance with the Wisconsin Department of Transportation’s three lane bridge criteria.

Staged construction was used to keep two lanes of traffic open during construction operations. Since crossovers were not used, the project included details for partial removal of the existing structures along with partial construction of the proposed structures.

The proposed structures were two-span, 45W prestressed girder bridges supported on a multi-column pier and full-retaining abutments. Spread footings were utilized at each substructure location. These bridges were designed in accordance with AASHTO’s LRFD Bridge Design Specifications.
