The Wisconsin Department of Transportation (WisDOT) announced nine Excellence in Construction Awards during its recent Contractor-Engineer Conference in Madison. Two of the winners included a concrete paving project in the Village of Sister Bay and a multi-use trail in the City of Sheboygan – both projects involved engineering, planning, and design work by Donohue & Associates. Vinton Construction Company of Manitowoc received the Excellence in Concrete Paving Award for the reconstruction of a three-quarter-mile segment of State Trunk Highway 42 in Sister Bay. Lunda Construction Company of Black River Falls received the Excellence in Construction of Unique Projects Award for a new 2.6-mile bike and pedestrian path in Sheboygan.
The Village of Sister Bay, along with the Wisconsin Department of Transportation, developed plans to reconstruct Bay Shore Drive (STH 42) through downtown Sister Bay. Donohue performed an alternatives analysis on various alignments for sanitary sewer, storm sewer, and water mains on STH 42 and then designed the selected alternative in advance of roadway reconstruction. The design consisted of 2,900 lineal feet of water main, 2,800 lineal feet of sanitary sewer main, and 1,500 lineal feet of storm sewers. This required relocating mains and private laterals that resulted in abandonment of 23,000 feet of existing sewers and associated structures. Construction took place during the fall and winter months to minimize the impact to the tourist-dependent businesses and to ensure the least disruption of traffic in Sister Bay. Donohue provided construction observation and administration during this phase. The corridor accommodates about 7,000 vehicles on an average day, but can experience twice that volume during peak travel periods.
Donohue was retained to design a multi-use path along the City of Sheboygan’s west side to provide pedestrian and bicycle accommodations, connecting the south and north ends of the city. The grade-separated path extends 2.6 miles and traverses steep terrain, heavy traffic, wetlands, utility corridors, and environmental corridors. Six structures were constructed to minimize impacts on adjacent properties and environmentally sensitive areas, including three retaining walls, two pre-fabricated pedestrian bridges (one is 185 feet long spanning the Sheboygan River and one is 154 feet long crossing over the Union Pacific Railroad), and one 1,000-foot long boardwalk through wetlands. The project was paid for with federal funds from the Non-Motorized Transportation Pilot Program.
