In [[Indiana]], I-80 runs concurrently with another Interstate Highway for its entire length. It runs with I-94 on the [[Borman Expressway]] from the Illinois state line to [[Lake Station, Indiana]], then with [[Interstate 90|I-90]] on the [[Indiana Toll Road]] from Lake Station to the Ohio state line.

Between [[La Porte, Indiana|La Porte]] and the [[Toledo metropolitan area]], I-80/I-90 is located within {{convert|10|mi|km}} of the [[Michigan]] state line but does not enter that state. From the [[Indiana State Road 9|State Road&nbsp;9]] (SR&nbsp;9) and I-80/I-90 interchange, the sign marking the Indiana–Michigan state line is visible. I-80/I-90 passes through the [[South Bend–Mishawaka metropolitan area]], passing the [[University of Notre Dame]] and the [[University Park Mall]], intersecting with the [[St. Joseph Valley Parkway]]. At another point in northern Indiana, I-80/I-90 comes within about {{Convert|200|yd|m}} of the Michigan border.<ref>{{Cite web|url=https://www.microsoft.com/en-us/research/|archive-url=https://web.archive.org/web/20120917161113/http://msrmaps.com/image.aspx?S=12&T=2&X=810&Y=5780&Z=16&W=2|url-status=dead|title=Microsoft Research – Emerging Technology, Computer, and Software Research|archive-date=September 17, 2012|website=Microsoft Research|access-date=June 6, 2020}}</ref>
