Jordan River is a creek that winds through the Indiana University campus. Originally the small creek was known as "Spanker's Branch", but over the years was colloquially renamed to "Jordan River" in honor of David Starr Jordan, and was formally renamed in 1994.
The Jordan River dives underground at 6th Street & Indiana Avenue just north of Franklin Hall, and reappears through the "Spanker's Branch Arch" under a street on the south side of town. The culvert housing the Jordan River under Kirkwood Avenue was the project of the Big Dig of 2000. Chipotle rests on a major section of that construction.
