Reconstruct I-75 between Fifth Street and Riverview Avenue.  Replace the various left-sided and right-sided ramps with a single, centrally-located interchange for downtown Dayton.  The interchange will service movements to and from the following streets:

  • First Street
  • Third Street
  • Salem Avenue
  • Second Street
  • Monument Avenue
