Civil Case Studies
Donohue has performed civil projects throughout the Midwest. Several case studies are provided below. These demonstrate some of our civil engineering experience and expertise.
Prior to the reconstruction of STH 67 through downtown Plymouth, Wisconsin DOT and the City of Plymouth requested a study of alternatives routes.
Donohue designed two reinforced concrete box culverts on CTH O for consecutive crossings of the meandering Grandma’s Creek.
Donohue was retained to plan and design this roadway reconstruction project along a three mile corridor in the Town and City of Sheboygan.
Completed under a master design contract with Wisconsin DOT, this project included beam guard upgrades to meet current design standards at 161 sites on five multi-lane highways including I-39, I-90, and US 151.
The CTH OK/EE intersection improvement was initiated by Sheboygan County to address a hazardous safety concerns and significant crash history.
This pilot safety study analyzed the safety and operational deficiencies of 105 miles of roadway on seven county highways.
Donohue developed an urban street reconstruction project through downtown Elm Grove that included new pavement from business front to business front, storm sewers, sidewalks and bike accommodations.
Donohue’s South Bend office designed a 2.0-mile bike path to provide recreational opportunities for bicyclists and pedestrians.
Donohue was retained to design the 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 10-foot wide, grade separated asphalt path extends a total of 2.6 miles with a 14-foot wide section along the steep hills south of the Sheboygan River.
La Crosse County is known for its majestic bluffs and coulees that define its landscape. That topography is also responsible for blind curves and steep slopes that create hazardous highway conditions. Donohue conducted a phased two-year safety evaluation of all 250 miles of county highway. This project was the first county-wide comprehensive safety evaluation in the state.
