The last and newest section of Interstate Highway was completed 32 years ago. It never reached the West Coast.
The Federal Highway Administration (FHWA) has claimed the section of I-70 through Glenwood Canyon in Colorado, completed in 1992, to be the last piece of the Interstate Highway System, as originally planned, to open to traffic.
