WIS 164 (County J), I-94 - WIS 175 - Environmental documents, Final Environmental
Impact Statement (FEIS)
The Wisconsin Department of Transportation (WisDOT), in response to comments received from review agencies,
local units of government, interest groups and private citizens,
prepared a Record of Decision (ROD) for the WIS 164 project.
The ROD detailed
the features of the selected alternative, discussed the range and
magnitude of impacts associated with ultimate construction of this
alternative, and addressed comments on the FEIS, which was
completed in late 2001.
After coordinating with appropriate
review agency representatives, the ROD was finalized and forwarded to
the Federal Highway Administration (FHWA) for review and comment. FHWA
issued the ROD on March 6, 2006.
Based on FHWA's determination, the
environmental analysis and documentation phase of this project is now
complete. Commitments made in the FEIS
(including impact mitigation, design features, permit requirements
and others) were pursued during the design process.
Preferred improvement plan
identified for WIS 164/County J corridor
WisDOT, in consultation with the Federal Highway Administration (FHWA), identified the preferred improvement plan for the
WIS 164/County J corridor in Waukesha and Washington counties.
The 18-mile corridor
extends from Rockwood Drive just north of the I-94/County J
interchange to near County E, south of Ackerville.
Detailed information on the preferred
alternative, the basis for its selection, measures to minimize adverse
effects, and a summary of the public hearing testimony and comments
received during the public comment period were presented in the FEIS.
Some specific features of the preferred
The recommended ultimate, long-term
improvement is a four-lane divided roadway with a 30-foot-wide
grass median separating northbound and southbound travel lanes.
In segments where traffic will be
below the 13,000 ADT threshold for the foreseeable future, the
four-lane improvements will be implemented through corridor
preservation and interim two-lane improvements will be
implemented when safety, pavement condition, and/or capacity
concerns indicate the need.
An urban typical section with
curb-and-gutter both inside and outside the travel lanes will be
constructed from Rockwood Drive to the vicinity of Howard Lane,
north of Sussex.
A hybrid typical section with
gravel shoulders and ditches outside will be constructed from
Howard Lane to near County E.
Plantings, small berms, landscaping
and other aesthetic treatments will be incorporated into the
project in some locations.
WIS 164 will pass over the Union
Pacific railroad crossing in Sussex.
The posted speed limit in the
southern eight miles of the study area between Rockwood Drive and
Sussex will drop to 45 miles per hour.
