Safety studies help communities determine operational deficiencies of rural and urban roadways and highways, analyzing existing roadway geometry to identify deficient horizontal and vertical curves and substandard sight distances. Crash rates and severity analyses can help to identify unsafe zones and improve traffic conditions. Donohue’s team of transportation engineers strive to make our roadways safe linkages within our communities.

County-wide Comprehensive Safety Study  Thumbnail

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.
