Many of the world's most famous bridges are made of steel. However, it is important to note that steel bridges are not only visually appealing; they are also generally stronger, safer, faster to build, require less maintenance, and are more flexible, making them ideal for earthquake-prone and high-wind sites. The Brooklyn Bridge in New York City and The Golden Gate Bridge in San Francisco are both made of steel and were built in the 1890s. Both bridges are very similar in design and functioned as roadways until 1956 when The Brooklyn Bridge was converted into a pedestrian bridge. Today, the Brooklyn Bridge is still used by pedestrians and cyclists. The Hoover Dam on the Colorado River is another example of a major steel structure being used as a bridge before it was officially designated as one. The Hoover Dam Bridge connects the Nevada side of the dam with the city of Las Vegas. It opened in 1931 just months after the completion of the dam itself! Finally, we have the Walt Disney World Swan and Dolphin Resort Bridges. These two bridges connect the Disney property with downtown Orlando and were constructed in 1990. They are made of glass fiber reinforced plastic (GRFP) and measure 1 mile each. The GRFP material was chosen because it is much lighter than other options such as steel or concrete. This article shows that bridges can be flexible in design and use throughout history.
