This study, a 40 mile segment of 4-lane roadway, was initiated by legislative mandate to determine how to
best meet the long-term transportation needs of this corridor.
When corridor study limits are this large, a tiered environmental
process is preferred. The tiered process is used to eliminate repetitive discussions of the same issue and to focus on the actual
issues at each level of environmental review. It is
a means of accomplishing National Environmental Policy Act (NEPA)
requirements in as efficient a manner as possible.
selected a corridor for the 4-lane roadway to follow and an
Statement (EIS) for that corridor was completed in 2007.
Tier I focused on
the broad issues such as general location, facility type, mode
choice, area-wide air quality and land use implications of the
Each of the Tier II studies (see segments below) are a more
detailed analysis of segments of the Tier I
Corridor Study that address site-specific details of project
impacts, costs and mitigation measures.
Deer Lake - 200th St. to 120th St., Polk County – Currently in
Range - 120th St. to 15th St., Polk County – Not currently
Turtle Lake/Almena - 15th

Enough detail of a preferred design is
completed to enable the official mapping of the future
right of way.
Each Tier II segment takes approximately two years to complete with
Tier II scheduled to be completed by 2015.
Tier III is the final design and construction. In order to advance
to this tier, the legislature needs to approve funding.
