I-75 at the north end of Interstate 375 by Downtown Detroit, Michigan. 11/06/11

Interstate 375 is the shortest signed route within the Eisenhower Interstate System at 1.06 miles. I-878 in Queens, New York is shorter, but the route is not signed. This will eventually change with plans advancing to convert I-375 in Detroit to an at-grade boulevard.

Wis 78 north ends at the merge point of Interstate 39 south with I-90/94 east near Portage, Wisconsin. 06/15/15

There are two three-way overlaps in the Interstate System at present: I-39, I-90, I-94 between Portage and Rockford, Illinois and with the 2015 designation of I-41, I-41, I-43, I-894 along the Airport Freeway in Milwaukee. A third set will be created once I-69 is completed from Bloomington to Indianapolis along I-74/465.

Interstate 5 passes through Downtown San Diego’s S-curve below the Sixth Avenue over crossing. 07/13/06

Prior to its retraction in 1964, Interstate 5 through San Diego was signed as U.S. 101. The majority of California’s U.S. highways were whole sale replaced by the Interstate system.
