The first step
The process of
improving I-70 began in 1999, when MoDOT conducted a feasibility
study to document the condition of the highway and to identify a
number of alternatives in response.
Selecting the best improvement strategy
January 2000, MoDOT launched the I-70 Improvement Study,
an environmental impact study that evaluated several improvement
strategies, including widening and reconstructing the interstate,
building a completely new interstate parallel to the existing one
or introducing enhanced transit options. Completed in December 2001,
the I-70 Improvement Study determined that the
best strategy for improving I-70 and preparing it for the future
was to widen and reconstruct it (see video clip on this page or
study documentation in Corridor Documents).
Taking the next step
was launched in 2002 and included a more detailed analysis
of the selected strategy. This phase ensured that the improvement
strategy would be implemented in a way that is sensitive to the environment
and responsible to the communities and individuals that will
from this major investment of the state's resources. The Improve I-70 Second Tier studies provided
more information on the location, basic design, environmental
and cost of I-70 improvements. Completion of this phase set
the stage for future steps toward design and construction.
