How Long Did It Take to Build the Mackinac Bridge?

The Mackinac Bridge is one of the most iconic structures in the United States and it has been connecting the Upper and Lower Peninsulas of Michigan since 1957.

The bridge is an incredible engineering feat that spans over five miles and is the longest suspension bridge in the Western Hemisphere. But how long did it take to build the Mackinac Bridge?

The construction of the bridge began in 1953, and the project was completed in 1957. The total time to construct the Mackinac Bridge was a total of four years. It took over 20,000 workers and 3,500 pieces of equipment to construct the bridge.

The total cost of the project was over $100 million. The first step of the bridge construction was the construction of two towers that would support the bridge.

These towers were built with reinforced concrete and steel and were about 550 feet tall. The towers were completed in January of 1955, after about two years of construction.

The next step of the construction was the laying of the bridge deck. This process took about a year and a half, and it involved connecting the two towers with steel cables that were suspended from the towers. The deck was connected to the towers with steel anchorages and was completed in August of 1956.
