St. Ignace (Upper Peninsula) | Total Length: 26,372 feet (nearly 5 miles) per [Wikipedia](https://en.wikipedia.org/wiki/Mackinac_Bridge) | Opened: November 1, 1957 | Total Crossings: 200+ million vehicles since opening per [Mackinac Bridge Authority](https://www.mackinacbridge.org/) | Operator: Mackinac Bridge Authority (MBA) | Payment: MacPass (E-ZPass compatible) or cash at toll plaza | Labor Day Bridge Walk: Annual event — limited bridge closure for walkers | High-Wind Closures: Sustained winds over 45 mph / gusts over 65 mph trigger closures | Camera Sources: MDOT, Mi Drive, Mackinac Bridge AuthorityThe Mackinac Bridge — affectionately called "Mighty Mac" — connects Michigan's Lower Peninsula at Mackinaw City to the Upper Peninsula at St. Ignace across the Straits of Mackinac, carrying Interstate 75. Per Wikipedia's Mackinac Bridge entry, the bridge's total shoreline-to-shoreline length is 26,372 feet (8,038 m) — just 28 feet short of five miles. Opened November 1, 1957 (replacing a 50-year ferry service), the Mackinac Bridge is operated by the Mackinac Bridge Authority (MBA) and carries over 200 million total crossings in its history. The bridge is subject to episodic high-wind closures — sustained winds over 45 mph or gusts over 65 mph trigger restrictions or full closure. Michigan winter conditions bring snow, ice, and visibility issues through most of the crossing season.

VIEW MACKINAC CAMERAS →High-Wind Closure Protocol
Per the Mackinac Bridge Authority, the bridge can impose restrictions or full closure based on wind conditions:
- Sustained winds over 20 mph: empty motorhomes, mobile homes, and tractor-trailer combinations are escorted across
- Sustained winds over 35 mph: high-profile vehicles are prohibited
- Sustained winds over 45 mph / gusts over 65 mph: full closure
Winter lake-effect snow and ice storms can close the bridge for hours. Check cameras and MBA current status before heading to the Straits.
Pro Tip: Payment + Historic Context
MacPass is the Mackinac Bridge Authority's electronic toll transponder — compatible with E-ZPass and faster than cash payment. Cash is still accepted but slows the crossing. The initial 1957 toll was $3.25 per car, equivalent to approximately $37.26 in 2025 dollars per Wikipedia — a reminder that tolls have actually declined in real terms thanks to 67+ years of amortization.
For Mackinac Island access, the bridge does not go to the island itself — ferries depart from both Mackinaw City and St. Ignace.
