History - Sauk City to Middleton:
Date |
Activity |
1991 |
US 12 Study Committee provides recommendations to Wisconsin State Legislature. The recommendations were to provide a four-lane divided highway, a Middleton bypass and a second bridge crossing to Sauk City. Over half of the public written responses obtained at the public informational meeting held in 1991 favored a four-lane improvement. Another 14 percent believed that some type of improvement was required but were concerned about the long-term effects of a four-lane highway. The remaining respondents opposed a four-lane improvement and favored no improvement at all or spot up-grades to the existing two-lane roadway. |
1993 |
Public responses obtained during public informational meetings held in 1993 were similar to the 1991 written responses. US 12 project is enumerated by the state legislature, this allows WisDOT to spend funds set aside for major highway projects. |
April 19, 1995 |
Draft EIS signed. |
May 1995 |
Public hearings are held on the DEIS in Sauk City and Middleton. |
1996 |
Public hearings on Supplemental Draft EIS are held in Sauk City and Middleton. |
November 5, 1998 |
Final EIS approved by the Federal Highway Administration |
1999 |

MOA sets framework for mitigation measures. |
