61sign U.S. Highway 61 - Interstate Upgrade Timeline

The following timeline gives the dates when sections of U.S. 61's route were moved onto the Interstate Highway System; the dates do not necessarily refer to the year the freeway was completed.

I-35 generally replaced U.S. 61 between the town of Wyoming in the northern Twin Cities metro and the city of Duluth. U.S. 61 was concurrent with I-35 on this stretch until the AASHTO approved U.S. 61's retirement north of Wyoming in 1990.

Interstates 90 and 94 replaced only short stretches of U.S. 61's historic route. I-90 replaced the old two-lane road in the Mississippi River Valley through the towns of Dresbach and Dakota. I-94 replaced the old divided highway on the east side of St. Paul between Johnson Parkway and Mounds Boulevard.
