Baker to design Daniel Hoan Bridge upgrade
Wisconsin Department of Transportation (WisDOT) has awarded Michael Baker Jr the preliminary design contract for the US$8.8 million improvement and reconstruction of the Daniel Hoan Bridge and the I-794 Freeway.
Design services cover structures, the roadway, traffic, surveys, public involvement, environmental, geotechnical and lighting work. Preliminary design is expected to take approximately eight months.
Reconstruction costs are estimated to be about US$350 million. The project is divided into three major segments. Bridges will be removed and replaced with new structures in the I-794 East-West section from Milwaukee River to the Lake Interchange. Bridge decks will be repaired and overlays applied in the Lake Interchange section from I-794 East-West to the Hoan Bridge. In the Hoan Bridge section of the freeway, bridge decks will be replaced and existing steel structures will be repaired and repainted. Structural modifications will also be made to the Hoan Bridge to extend the remaining service life to approximately 40 to 50 years.
