Recommended Concept
Conceptual Study Report
After the completion of the Future 64 Planning and Environmental Linkages Study, MoDOT and its partners moved forward to determine the recommended concept for the I-64 Central Corridor. Taking the three options shared at the end of the Future 64 PEL, this portion of the evaluation took the portions of the options that the community and the stakeholders liked and created a recommended concept for the corridor. Engineers evaluated the concept to verify that it can be built, that it meets current roadway standards and that it best supports the vision of the community.
All future construction will need to be funded, through various sources, and will still need to go through some form of public outreach to ensure that the work still adheres to the project needs and goals, as outlined by the community and other stakeholders.
As a part of that, the department developed the following document:
