The section of Interstate 73 between Marion and Circleville was the most complicated section to plan. The red line is the final routing that was agreed on in 1996, and the blue line was the only other route that was under serious consideration when the map was completed in 1995. The west side of Columbus has a watershed that is protected (Big and Little Darby Creeks), so that all but eliminated any western routing, and the far eastern route would be too expensive due to all the new construction required. The question was whether to build along U.S. 23 and tear up all the businesses along it or multiplex it with Interstate 71. Note that Interstate 73 was not considered to be routed along Ohio State Route 315.
