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
More people means more cars and trucks on the highway.
Traffic congestion and safety are now critical issues.
2006 traffic volumes, Capitol Drive - Sussex,
ranges from 13,000 - 15,400 vehicles on weekdays.
Traffic, Capitol Drive - 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.
