The Sunshine Skyway Bridge, located in Tampa, Florida, is a iconic and vital transportation artery that has been in operation since 1987. This massive steel bridge spans the Lower Tampa Bay, connecting St. Petersburg to Terra Ceia, and has become an integral part of the region's infrastructure. Here are five interesting facts about the Sunshine Skyway Bridge:
Design and Construction
The Sunshine Skyway Bridge was designed by the engineering firm of Figg & Muller, and its construction was a significant undertaking that required the use of advanced technologies and techniques. The bridge’s main span is 1,200 feet (366 meters) long, and its total length is approximately 4.1 miles (6.6 kilometers). The bridge’s height above the water is 190 feet (58 meters), allowing large ships to pass beneath it. The construction of the bridge took nearly four years to complete, from 1982 to 1986, and cost around $244 million.
Structural Features
The Sunshine Skyway Bridge is a cable-stayed bridge, with a unique design that features a single tower supporting the main span. The tower is 430 feet (131 meters) tall, and is anchored to the seafloor with a series of deep foundations. The bridge’s deck is supported by a system of cables and suspender cables, which are attached to the tower and the bridge’s piers. The bridge’s structural system is designed to withstand extreme weather conditions, including hurricanes and earthquakes.

| Total Length | 4.1 miles (6.6 kilometers) |
| Height Above Water | 190 feet (58 meters) |
| Tower Height | 430 feet (131 meters) |
History and Significance
The Sunshine Skyway Bridge has a rich history, dating back to the 1950s when the original Skyway Bridge was constructed. The original bridge was a steel truss bridge that was built in 1954, and it played a critical role in connecting the cities of St. Petersburg and Terra Ceia. However, the original bridge was closed in 1980 after a freighter collided with one of its support columns, causing a section of the bridge to collapse. The current Sunshine Skyway Bridge was built to replace the original, and it has become an iconic landmark in the Tampa Bay area.
Environmental Impact
The Sunshine Skyway Bridge has had a significant impact on the environment, both positive and negative. On the one hand, the bridge has improved transportation efficiency and reduced travel times between St. Petersburg and Terra Ceia. On the other hand, the bridge’s construction has altered the natural habitat of the Lower Tampa Bay, and has had an impact on the local marine ecosystem. However, the bridge’s design incorporates features that minimize its environmental impact, such as a system of artificial reefs that support marine life.
