Additional ramps at US 12 /County NN Interchange to close long-term
Overnight ramp closures in advance of next week’s long-term closures


Feb. 8, 2016

On Monday, February 15, the Wisconsin Department of Transportation is planning long-term closures of the westbound US 12 off-ramp to County NN and the County NN on-ramp to eastbound US 12. These closures are part of the US 12/County NN Interchange reconstruction project. The aforementioned ramps, along with the County NN on-ramp to westbound US 12 and the eastbound US 12 off-ramp to County NN, both of which closed last week, are scheduled to reopen mid-summer of 2016.

      Westbound US 12 off-ramp to County NN - long term closure traffic detour:
Traffic heading westbound on US 12 intending to exit at County NN will be directed to exit US 12 at I-43 southbound. Traffic will head southbound on I-43 and exit at WIS 67 (Lincoln Street). After exiting, traffic will continue north on Lincoln Street until reaching the County NN (Geneva Street) intersection. At the intersection, traffic can head east or west on Geneva Street.

Eastbound US 12 on-ramp from County NN - long term closure traffic detour:
Traffic intending to exit County NN (Geneva Street) onto eastbound US 12 will be directed west onto County NN until the WIS 67 (Lincoln Street) intersection. Continue to head south on Lincoln Street until the WIS 67/I-43 interchange where traffic can choose to head north or south on I-43. Northbound I-43 traffic will be directed to exit at the I-43/US 12 interchange where traffic will be able to choose either the US 12 eastbound or westbound ramp.
On February 9 -11, and 15, there will be also be overnight closures of virtually every ramp in the Interchange. These short-term closures are scheduled from 9 p.m. to 6 a.m.
Please note, the detour for the overnight ramp closure for westbound US 12 to County NN, differs from the ramp’s long-term closure detour. To learn more about the overnight closures and related detours, please visit
