February 1, 1967
Michigan became the first state to have a border-to-border interstate freeway.
A 7-mile section of Interstate 94 opened through St. Clair Shores and Roseville completed the 275-mile highway that ran from New Buffalo on the west to Port Huron on the east. Completing I-94 made Michigan the first state in the nation to have a border-to-border interstate highway.
