Abstract
The CTH J/STH 164/STH 190 (Capitol Drive) intersection in Waukesha County was designed to be constructed as an at-grade intersection in 2004. The regional growth history and projected traffic volumes for the design year (2025) indicate that grade separation should be considered at this location. Four interchange alternatives were designed at a planning level based on topography, major traffic movements, uniformity with local interchanges, and practical design guidelines. The first alternative was a single-point urban intersection (SPUI), the second alternative was a diamond interchange, the third alternative was a partial cloverleaf with loop ramps in the northeast and southeast quadrants, and the fourth alternative was a partial cloverleaf with loop ramps in the northeast and southwest quadrants. The interchange alternatives were analyzed based on right of way impacts, and traffic operations. The final result was a relative comparison of costs and cost savings associated with each alternative, and compared to the impacts of the at-grade intersection. The comparison showed that three of the alternatives may be reasonable for this location, and that one of the alternatives is not appropriate because of impacts.
