US 18/151 Freeway Conversion Study - Maps

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 improvement alternatives under consideration are shown on six separate maps. The six sections are labeled by number from west to east and by location limits. A brief description of the alternative(s) being considered within each section is also provided. In Section 2, Alternative 2B has been selected as the preferred option and is labeled as such.

Within each section, most of the new or realigned local road connections are the same in each of the alternatives. However, 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.
