South County Line Road Bridge Replacement
Client: Manitowoc County Highway Department, Wisconsin Department of Transportation
Location: Town of Meeme, Wisconsin
Donohue designed an 80-foot, two-span concrete flat slab bridge and 250 feet of roadway approach improvements. Alternative analysis was made to determine whether the bridge should be a single or two-span structure based on hydraulic and economic considerations. Tasks included hydrologic analysis and hydraulic modeling to verify the proposed bridge at the 100-year flood event meets backwater regulations.
Donohue’s work also included structural design, agency coordination, wetland mitigation, right-of-way platting, Wisconsin DNR/U.S. Army Corps of Engineers permitting, utility coordination, and public information/involvement activities. The design was prepared according to WisDOT specifications and LRFD procedures.
