 The original highway turned south from Edmond going into Oklahoma City, but the main route was moved onto Interstate 35.The beginning of the business route was at Lincoln Boulevard (in a concurrency with U.S. Route 77), leaving the main route on Interstate 440 (now Interstate 44).At 23rd Street (in front of the State Capitol), the two routes formed a tri-plex with U.S. Route 270 and turned west.
