• Proposed changes (1.1 MB)

The Dane County north segment of the US 51 corridor from just north of WIS 19 interchange to Grinde Road will be expanded from a 2-lane highway to a 4-lane freeway.

Access to US 51 will only be allowed at interchanges. Two full diamond interchanges located at Windsor Road and North Street/County V are included in the proposed design.

Other features of design are identified below and can be seen on the proposed changes map above:

• The proposed design will utilize the existing US 51 roadway on the north and south end as one roadway while an additional 2-lane roadway will be constructed along side.
• From Windsor Road to County V/North Street, all four lanes will be constructed east of existing US 51, and existing US 51 will be converted to a frontage road called North Towne Road. All driveways and side road access points on the west side of existing US 51 will maintain access to North Towne Road.
• Roundabouts will be constructed at the ramp terminals of the Windsor Road and County V/North Street interchanges, as well as on the north and south ends of proposed North Towne Road.
• County V will be realigned east of US 51 between North Street and County V (east).
• Overpass structures will be constructed at proposed Bear Tree Parkway and Vinburn Road. Side roads that currently intersect US 51 that will not have overpasses constructed, will become cul de sacs. These side roads are Reardon Road, Gray Road (west), and Grinde Road.
