US 12 Corridor Study
Fort Atkinson-Whitewater, Jefferson County

Study location

US 12, WIS 26 (near Fort Atkinson) to Whitewater, in Jefferson County.

Study overview

US 12 is classified as a Corridors 2020 Connector Highway and is also part of the National Highway System. Connector routes are vital links for regional traffic within the state’s overall roadway system. Regional trips are those that pass through, but are not destined for, a given location such as the city of Fort Atkinson.

The portion of US 12 within Fort Atkinson, must also act as a local street. Local trips begin and/or end somewhere within the city and involve turns on and off US 12 as well as parking maneuvers parallel to through traffic.

As volumes of both types of traffic increased, the ability of US 12 within Fort Atkinson to efficiently serve these two conflicting uses has declined.


Note - WisDOT has stopped all work on the study of a future US 12 Bypass through the town of Koshkonong south of Fort Atkinson. The final disposition of the study will be determined at a future date by the Transportation Projects Commission. (May 3, 2012)
