WIS 26 corridor EIS - Selection of preferred alternative, South segment
The south segment begins at the I-90 interchange at Janesville
and ends at the south Fort Atkinson Bypass interchange. This segment
is about 13.6 miles in length, and includes the city of Milton.
The preferred alternative is S3, the near east Milton bypass
corridor. Selection was based on local community input, public
comment, agency coordination, engineering analysis and environmental
A near east Milton bypass alternative is preferred as it provides
transportation and other benefits that an alignment through the
eastern part of Milton does not provide, including:
The preferred easterly route is a more direct north-south
route with fewer curves. In particular, it eliminates the need
for an S-curve alignment between the two Milton interchanges
that were necessary under the other alternative.
The preferred route is 0.6-miles shorter. Accordingly, it
takes about 30 acres less total land, and 22 acres less
farmland, than the other alternative.
The preferred route impacts two less farm parcels than the
other route, and has a lesser overall farmland impact as the
route does not sever farm fields on a diagonal leaving more
difficult pie-shaped remnants for farming operations.
The preferred route adjacent to the Storrs Lake Wildlife Area
acts as a buffer between urban development and the wildlife
area. Existing and future development will be contained entirely
west of the roadway, and open space/hunting grounds (Storrs Lake
Wildlife Area) east of the roadway. The other alternative allows
development to occur east and west of the roadway with limited
access across the roadway.
The preferred route is similar to a corridor placed on
Milton's official map in the 1970's in anticipation of a
possible future bypass need for Milton. While the corridor was
removed from the official map in the 1990's due to a request to
create a rural subdivision next to the Storrs Lake Wildlife
Area, much of the land within the corridor remained undeveloped.
At this time, 45 out of a potential 52 lots in the subdivision
The preferred route requires 17 relocations as compared to 51
for the other alternative. While 40 of the 51 relocations are
residential tenants in five 8-unit apartment buildings, the real
estate acquisition and relocation costs for both alternatives
are about the same.
The preferred route has a total construction and real estate
cost that is approximately $3 million less than the other
alternative. It is expected to have less future maintenance
costs due to its more direct north-south routing, shorter
overall length, and fewer bridges.
