WIS 29 freeway conversion study - access types

Designating WIS 29 as a freeway could change how some local and county roads connect to WIS 29. Proposed changes would not occur for 10 to 20 years and would involve the public's input. 

The image below shows the different types of highway access while the text following the image gives a description of each type of highway access.

• At-grade crossing: Traffic on the intersecting roadway must stop at the highway intersection. Traffic may proceed when the highway lanes are clear or, at a signalized intersection, when the light turns green.
• Cul de sac: The intersecting roadway is closed off to through traffic. 
• Overpass: The intersecting roadway is built over the highway to allow continuous traffic flow. Traffic on the intersecting roadway can not access the highway from the overpass. 
• Underpass: The highway is built over the intersecting roadway to allow continuous traffic flow. Traffic on the intersecting roadway can not access the highway from the overpass. 
• Interchange: The intersecting roadway is built over the highway with ramps, giving motorists the option to smoothly enter the highway or remain on the intersecting roadway.
