Interstate 75 (I-75) is a part of the Interstate Highway System and runs from Miami, Florida, to Sault Ste. Marie in the Upper Peninsula of Michigan. I-75 enters the state from Ohio in the south, just to the north of Toledo, and it runs generally north through Detroit, Pontiac and Bay City, crossing the Mackinac Bridge and ends at the Canadian border in Sault Ste. Marie. The freeway runs for approximately 395 mi on both of Michigan's two peninsulas. In the 1950s, a north–south Michigan Turnpike was proposed as a tolled, controlled-access highway in the Lower Peninsula. After passage of the Federal Highway Act of 1956, this turnpike proposal was shelved as a free Interstate Highway was planned instead. Construction started in 1957, signs went up in 1959, and I-75 was completed in 1973. Since completion, the freeway has been upgraded with the construction of the Zilwaukee Bridge near Saginaw and improved connections to the Ambassador Bridge in Detroit. (more...)
