WIS 164 study

Traffic on WIS 164 has been studied since the 1960s. At that time traffic clearly called for a two-lane county highway. By the 1990s, population had dramatically grown in Waukesha and Washington counties.

More people means more cars and trucks on the highway. Traffic congestion and safety are now critical issues.

2006 traffic volumes from Capitol Drive to Sussex ranges from 13,000 to 15,400 vehicles on weekdays. Traffic from Capitol Drive to I-94 is even greater, up to 23,000 vehicles on weekdays.

These volumes exceed federal standards for safe and efficient travel on two-lane urban highways. Traffic is expected to continue to grow 50 percent over the next 20 years.

Portions of WIS 164 have steep hills, blind intersections and many access points that affect safety and traffic flow.

A full range of improvements to WIS 164 have been studied. Citizens and public officials were asked to review, comment on and help determine the best approaches to these improvements.
