The Mackinac Bridge was designed by engineer David B. Steinman and architect Charles Ellet Jr.
In its design, the Mackinac Bridge incorporates several features that allow it to withstand the varying weather conditions in the Straits of Mackinac. These features include:
1. High-strength materials: The bridge's main towers and the steel used in its construction are designed to withstand strong winds, heavy snowfall, and loads from vehicles crossing the bridge.
2. Aerodynamic shape: The bridge is designed with a sleek, streamlined shape to minimize wind resistance. This reduces the impact of strong winds on the bridge structure.
3. Flexible suspension system: The Mackinac Bridge is a suspension bridge, and its main span is supported by steel cables. The flexibility of the suspension system enables the bridge to sway and flex with the wind, reducing the risk of damage caused by high winds.
4. Deep foundations: The bridge's towers have deep foundations that are anchored into the bedrock below the straits. This provides stability, especially during extreme weather conditions.
5. De-icing systems: The Mackinac Bridge has a de-icing system that prevents the accumulation of ice on the bridge's surfaces. This helps maintain traction and prevents ice-related issues during winter.
Overall, the combination of these design features allows the Mackinac Bridge to withstand the varying weather conditions, making it a safe and reliable structure.
