Mackinac Bridge, one of the most iconic landmarks in the United States, spans the Straits of Mackinac, connecting the Upper and Lower Peninsulas of Michigan. As a vital transportation artery, it has been a marvel of engineering since its completion in 1957. One of the most frequently asked questions about the bridge is its length. In this article, we will delve into the details of Mackinac Bridge mileage, its history, construction, and interesting facts.
History of Mackinac Bridge
Before the construction of Mackinac Bridge, the only way to travel between the Upper and Lower Peninsulas of Michigan was by ferry. However, as the region's population grew, so did the need for a more efficient and reliable transportation system. In 1920, the Michigan State Legislature authorized the construction of a bridge across the Straits of Mackinac. However, due to funding issues and the Great Depression, the project was delayed until 1953, when construction finally began.
Construction of Mackinac Bridge
The construction of Mackinac Bridge was an engineering feat of its time. The bridge was designed by engineer David B. Steinman and took nearly four years to complete. It was constructed using a innovative technique called the "deflection theory," which allowed the bridge to flex in strong winds. The bridge's main span is 3,800 feet (1,158 meters) long, and it stands 552 feet (168 meters) above the water.
How Long Is Mackinac Bridge?
The total length of Mackinac Bridge is approximately 26,372 feet (5 miles or 8 kilometers) long, making it one of the longest suspension bridges in the world at the time of its completion. The bridge's length is divided into five sections: the north anchor span, the north tower span, the main span, the south tower span, and the south anchor span.
Interesting Facts About Mackinac Bridge
Here are some interesting facts about Mackinac Bridge:
- Mackinac Bridge is often referred to as the "Mighty Mac."
- The bridge's towers are anchored in bedrock, 190 feet (58 meters) below the surface of the water.
- The bridge's roadway is made of steel grating, which allows for drainage and reduces the weight of the bridge.
- Mackinac Bridge is painted every 10-15 years to protect it from corrosion.
- The bridge's annual maintenance cost is approximately $10 million.
Mackinac Bridge Maintenance
Maintaining Mackinac Bridge is an ongoing process. The Mackinac Bridge Authority, the organization responsible for the bridge's maintenance, uses a variety of techniques to keep the bridge in good condition. These techniques include:
- Painting the bridge to protect it from corrosion
- Replacing the bridge's suspension cables
- Inspecting the bridge's structure and making repairs as needed
- Cleaning the bridge's roadway and sidewalks
