US 51, from just north of WIS 19 interchange to Grinde
Rd., will be expanded from a 2-lane highway to a 4-lane freeway.
US 51 will only be allowed at interchanges. Two full diamond interchanges located at Windsor
Rd. 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 Rd. 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
Rd. All driveways and side road access points on the west side of existing
US 51 will maintain access to North Towne Rd.
Roundabouts will be constructed at the ramp terminals of the Windsor
Rd. and County V/North Street interchanges, as well as on the north and south ends of proposed North Towne
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 Rd. Side roads that currently intersect US 51
that will not have overpasses constructed, will become
cul-de-sacs. These side roads are Reardon Rd., Gray Rd. (west),
and Grinde Rd.
