Why is MoDOT doing this project?

The project area is located in the heart of Clay County, the seventh most populous county in Missouri and one of the fastest-growing counties in the state.

The existing interchange and the current traffic volumes significantly impact the travel times. Improving I-35 from I-435 to Pleasant Valley on the north is a significant community priority that the Cities of Pleasant Valley, Liberty, and Kansas City as well as the Village of Claycomo support.

How will this project benefit me?

Long-term benefits from improving the interchange and nearby cross streets will reduce travel time and vehicle operating costs for business and personal travelers. Along the interstate, continuous ramp lanes will be constructed at both the north and south ends of the project.

The ramp lane improvements will allow traffic along both northbound and southbound I-35 to smoothly merge with traffic coming from the I-435 interchange.

What is the project timeline?

Construction activities are anticipated to begin in early 2015 and all new pavement open by the end of May 2017. All construction will be complete by the fall of 2017.

How is the project funded?

The project is funded with a combination of federal, state, and local funds that have been brought together as a cooperative cost-share project. The detailed breakdown of the $40.5 million corridor project includes:

  • MoDOT (state and federal funds) = $32,100,000
  • City of Liberty = $4,200,000
  • City of Pleasant Valley = $100,000
  • MARC (regional federal funds) = $5,000,000
