Between 2010 and 2014, The Missouri Department of Transportation (MoDOT) conducted an environmental study of I-70 in Jackson County. The study is a Second Tier Environmental Impact Statement (EIS) for the future I-70 from The Paseo interchange to the Blue Ridge Cutoff interchange.
Why did MoDOT do the study?
I-70 is a critical regional and state corridor that was originally constructed over 50 years ago. With proper maintenance, this facility has outlasted its original design life of 20 years. The stretch of I-70 in the study is currently experiencing deteriorating pavement and bridges, traffic delays and congestion, and merging and weaving at interchanges.
The Second Tier EIS will build on and extend the work of the I-70 First Tier EIS for future I-70 that results in the best possible plan to improve the safety and conditions of I-70.
The study resulted in suggested improvements totaling $265 million and included everything from the bus-on-shoulder concept to reduce congestion to completely rebuilding the I-435 and I-70 interchange. See a complete list of preferred changes.
What is the study area?
The study area includes all land within 200 feet of the I-70 First Tier EIS Selected Strategy (Improve Key Bottlenecks) defined footprint from west of The Paseo interchange to east of the Blue Ridge Cutoff interchange in Jackson County, Missouri. Download the study area map here.
What is the project timeline?
The study lasted 34 months and concluded in summer 2014.
Will the study lead to construction projects?
Since the beginning of the study, some of the recommendations have been complete or in the design phase. For example, rebuilding the bridges at Manchester Trafficway was complete in December 2015. Rebuilding the I-435 and I-70 interchange to remove left-hand exits is currently in design. Review all of the recommendations for improvement and leave your comments!
Developing transportation improvements involves four phases:
The I-70 Second Tier EIS is in the environmental phase. The remaining design and construction phases are contingent upon available funding. Anywhere from a few to many years could be needed to complete the entire process.
