I-270 North Environmental Assessment

 

Previous Planning

Prior to the I-270 North Environmental Assessment, the Missouri Department of Transportation conducted an 18-month high-level feasibility study called the I-270 North Corridor Study. It studied the area between James McDonnell Boulevard and Route 367. The feasibility study identified several problems (or concerns) along the corridor:

  • Limited capacity on I-270
  • Congestion; closely-space interchanges
  • Poor access for metro transit users, bicyclists and pedestrians
  • Confusing two-way cross-over slip ramps to Dunn Road
  • Aging infrastructure

At the end of the feasibility study, MoDOT wrote a final report highlighting the needs, problems and opportunities along the I-270 North Corridor between James McDonnell Boulevard and Route 367. The conceptual drawings developed during the study illustrate the strategies for the corridor They do not indicate the exact locations or needed right-of-way for any possible further construction. During the I-270 North Environmental Assessment, the improvement concepts will be further evaluated. The final report and conceptual drawings can be downloaded here.

This study was the first step in the project development process.  The I-270 North Environmental Assessment is the next step. At this time, no funding is available for design, right-of-way or construction.
