The Interstate System In Indiana

Today (10 February 2020) marks the first anniversary of Indiana Transportation History in blog form. The first post went up one year ago at 0446, which is three hours and 46 minutes from when this post goes live. The six days a week started a year from tomorrow (11 February 2019). Thank you for sharing the past year with me.

Today, I want to focus on the interstate system in Indiana. There were several ways I was going to do this…and finally decided that I would just do a chronological list of how the system was created in Indiana. The information contained in this post comes from the Indiana State Highway Official Maps as released by the State Highway Department (1960) and the Indiana State Highway Commission (1961-1977). Keep in mind that the information was passed along through the official maps was usually the year after the actual completion. For example, the “innerloop” of I-65/70 in downtown Indianapolis was opened in late 1976. It appeared on official maps in 1977, although the map itself was actually printed in 1976.

The first interstate in Indiana really is a matter of discussion. The Indiana Toll Road, which would become (according to the map of 1960) I-80/90/94 was built in the mid-1950’s. It was actually completed from state line to state line before the Interstate system came into being. Another contender would be I-65 at Lebanon. Construction on I-74 east of Indianapolis was started in 1959, with the road opening in October 1960 from southeastern Marion County to SR 9 north of Shelbyville. Construction on I – 74 from the Illinois-Indiana state line east to between Covington and Veedersburg was also listed as under construction in 1959, completed in 1960. After I – 90, which would be the route of the Indiana Toll Road across Indiana, I – 74 was the first that was completed. Technically, I – 90 wasn’t completed across the state until 1965, since before that, what is now the Tri-State (I-80/I-94) was actually part of I-90, and what is now I-90 west of Portage was I-94. The following year (1966), I-74 was completed across Indiana.

Now, there are additional interstates that have been added to Indiana since the end of this timeline: I – 469, the Fort Wayne beltway; I – 164, the Evansville access to I-64, which is now a part of I-69; I – 865, the original I-465 that became “the dogleg” for many years; and, of course, the I-69 extension, which as of this writing extends from Martinsville to Evansville. There is also the outside possibility that should US 31 be completed to interstate standards between Indianapolis and South Bend, which is slowly becoming a reality, it will receive an interstate number, as well. I am not holding my breath.

  1. It is interesting to see to see that without the technology of today, the interstate system was designed and built is less time than it would take if it were done today. Note: I-69 from Indy to Evansville.

    Great job Richard!

  2. I-64 was completed across Indiana in September of 1976 (I think the exact date was September 15). I worked at Indiana State Highway Commission at that time.
