I-43 (Rock Freeway): Elm Ridge Road Bridges
DAAR was selected by the Wisconsin Department of Transportation (WisDOT) to provide design services for the rehabilitation of twin bridges on I-43 outside of the City of Delavan, WI.
The structure work consisted of scoping for the redecking of two 3-span prestressed concrete girder structures carrying I-43 over Elm Ridge Road, and preparation of the structure survey reports and supporting materials.
DAAR was responsible for all tasks, related to roadway design and coordination, to take the project thru the WisDOT design process. This effort included field survey, environmental coordination, design reports, preparation of preliminary and final plans, traffic control/staging design, development of PS&E documents and coordination with the Bureau of Structures for the WisDOT prepared bridge plans.
This project carried an extremely aggressive design schedule as only eight months were allocated in order for the northbound bridge deck to be replaced during the 2015 calendar year. The scope of work to be completed was not abbreviated, as field survey work needed to be completed by DAAR in late 2013 for the design of the roadway and bridge decks to begin in early 2014. Coordination with the Bureau of Structures was an ongoing task as the bridge and roadway designs had to be developed in tandem, versus the more traditional schedule of the bridge designs following the roadway design.
