It opened on Nov. 1, 1957, and a 1951 Chevrolet Styleline Deluxe station wagon was the first vehicle to cross the bridge. You can visit the Grand Rapids Public Museum and see this car on display.

The bridge is also famous for the Mackinac Bridge Walk, which began in June 1958. The walk started with 68 people crossing the bridge but attracted 85,000 in 1992 when President George H.W. Bush participated in the event and walked with the group.

The first incident on Sept. 22, 1989, initially had high winds to blame as the cause of the accident. However, investigators later discovered the driver was speeding, hit the median, lost control, and jumped the guardrail.

The second incident happened on March 2, 1997, when a driver intentionally drove his vehicle over the edge of the bridge. So neither incident involved wind.
