Project overview

  • The US 18/151 Freeway Conversion 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.
