The Brooklyn Bridge is perhaps the most famous bridge in the United States. The hybrid cable-stayed/suspension bridge spans the East River and was completed in 1883 to connect Manhattan and Brooklyn. The bridge was originally known as the New York and Brooklyn Bridge and the East River Bridge.
The Concord Covered Bridge over Nickajack Creek was built in 1872, The one-lane bridge, also known as Nicknack Creek Covered Bridge, is more than 130 feet long and 16 feet wide and is a part of the Covered Bridge area, so named for the bridge. An earlier bridge was built in the area in 1848, but troops under Union Gen. William T. Sherman burned the span on July 4, 1864. The current bridge was renovated and/or upgrated in the 1950s and again in 1999.
The most impressive railroad relic in Clarksville, Tenn., is the swing bridge over the Cumberland River. With stone pillars dating to 1859, the 678-foot-long bridge is normally more than 50 feet above the river and can swing to allow river traffic to pass when the water level is high.
The Golden Gate Bridge is an icon of San Francisco. The famed bridge opened on May 27, 1937. To experience the bridge’s magnitude, head to Fort Point. This well-preserved Civil War era post is located on the southern side of the Golden Gate strait at the entrance of San Francisco Bay.
When it opened in 1964, the Verrazano-Narrows Bridge was the world’s longest suspension span. The bridge was named after Giovanni da Verrazano. In 1524, he became the first European explorer to sail into New York Harbor. Its 693-foot-tall towers are 1 5/8 inches farther apart at their tops than at their bases because the 4,260-foot-long required engineers to take into the account curvature of the Earth. Each tower weighs 27,000 tons and is held together with three million rivets and one million bolts. Seasonal contractions and expansions of the steel cables cause the double-decked roadway to be 12 feet lower in the summer than in the winter.
The Waco Suspension Bridge opened to traffic in January 1870, making it roughly 13 years older than the more famous Brooklyn Bridge. The 475-foot-long bridge forever changed travel in the area. Built at an estimated cost of roughly $141,000 (estimates vary) and designed by Thomas M. Griffith, the bridge was the first major suspension bridge in the state of Texas.
