The US 18/151 Freeway Conversion Study will result in a plan for the eventual removal of all direct access by existing local roads and driveways onto US 18/151. When construction of all plan elements is completed, access to US 18/151 will be at highway interchanges only. Local access to the interchanges will be facilitated by new grade separated crossings over or under US 18/151 and by adding to and improving the existing local road system.

The recommended alternatives are shown on separate maps. The sections are labeled by number from west to east and by location limits. A brief description of the selected alternative for each section is also provided.

Note - The final locations of some local roads are still to be determined. Coordination with local stakeholders will continue until the design and location of the local road changes and all other plan elements is completed.
