Many bridges in America have interesting stories about how they were designed and how they’ve changed over time. Millions of people use them every day without noticing how beautiful they are or the significance of their journey.
A bridge is a structure that connects two or more places that are not close to each other. This is important because it helps to connect different parts of the world. The United States has a lot of famous bridges, including the Lake Pontchartrain Causeway – the world’s second-longest over Water Bridge.
There are some really long bridges in the United States. Some of them are even longer than the bridges you usually see across cities. Here is a list of the longest bridges in the United States.
Lake Pontchartrain Causeway
The Lake Pontchartrain Causeway in Louisiana is the longest bridge in the United States, with a total length of 38.44km. The bridge held the title of the world’s longest bridge from 1969 to 2011, when it was named the world’s longest sea bridge.
The Lake Pontchartrain Causeway, which spans Lake Pontchartrain between New Orleans and Slidell, was given the title of “world’s longest sea bridge” due to its length. The bridge currently ranks second in the world, after the Hong Kong-Zhuhai-Macao Bridge, and has helped travelers avoid a lengthy drive around the lake.
Seven Mile Bridge
This Florida bridge is 10.8 kilometers long and goes over the Moser Channel in the Florida Keys. It connects Knight’s Key to Little Duck Key and has an arc that includes a 65-foot clearance so that boats can pass underneath the bridge. The Seven Mile Bridge is a significant part of both the Overseas Highway and US Highway 1 and is also a popular cycling and pedestrian bridge. The newer bridge opened in 1982, while the older bridge was completed in 1912. This makes the Seven Mile Bridge one of the longest bridges in the United States, and unique in its design.
Manchac Swamp Bridge
The Manchac Swamp Bridge is a large, twin-concrete trestle bridge that spans a swamp in Louisiana. It is one of the longest bridges in the world and is a popular tourist attraction.
The longest toll-free bridge in the United States is located over the Manchac Swamp, and it is free for motorists to use. Some people have suggested that this bridge may be the longest toll-free bridge in the world, costing around $7 million per mile to construct.
General W.K. Wilson Jr. Bridge
This bridge is known locally as the “Dolly Parton Bridge” because of its striking weathering steel arches. It is a popular tourist destination due to its unique appearance. The Dolly Parton Bridge gets its name from the red light on the archways. People say that the archways make the bridge look like Dolly Parton’s figure. In 2014, the bridge was damaged by a crash and had to be closed down for a while.
Chesapeake Bay Bridge-Tunnel
The Chesapeake Bay Bridge Tunnel was hailed as one of the most impressive engineering feats of the 1960s when it was completed. The tunnel is a 27.7-mile-long crossing between Virginia and Maryland and is made up of two tunnels: the lower tunnel, which is 16.4 miles long, and the upper tunnel, which is 9.3 miles long. The tunnel was designed by John A. Roebling and was considered one of the Seven Engineering Wonders of the Modern World. Thanks to this combination of Bridge and tunnel, you’re getting an extra hour and a half of time. And, like millions of other drivers, you’ve already crossed the bridge.
Atchafalaya Basin Bridge
The Atchafalaya Basin Bridge is a massive bridge that stretches 96,100 feet across the Atchafalaya River. It is one of the longest bridges in the world, and it is also one of the most impressive. When you’re driving through Louisiana, it can feel like you’re always on a bridge. This is especially true when you’re driving between Baton Rouge and Lafayette. The highway passes over the Atchafalaya Basin, one of the largest swamps in the United States. The swamp is home to many different plants and animals and is a popular spot for fishing and hunting.
Bonnet Carre Spillway Bridge
The I-10 Bonnet Carré Spillway Bridge is one of the longest bridges in the world, spanning a total of 17,702 meters or 58,077 feet. It is also one of the most technologically advanced bridges, being built with the use of the latest in engineering technology. Designed to carry the Lake Pontchartrain, Bonnet Carré Spillway, and LaBranche Wetlands inland, this bridge was commissioned in 972. The bridge is 11 miles long and crosses the Bonnet Carré Spillway, Lake Pontchartrain, and LaBranche Wetlands. It is the longest bridge in the United States.
The Spillway is a concrete bridge that diverts water from the Mississippi River into Lake Pontchartrain in order to prevent future flooding. The bridge is a twin trestle and guides Interstate 10 over the Spillway dike.
Louisiana Highway 1 Bridge
The Louisiana Highway 1 Bridge is a concrete trestle toll bridge in the United States that connects Leeville to Port Fourchon. It is located in Lafourche Parish, Louisiana, and was built in the 1930s. It is one of the older bridges in the area and has been subject to several repairs and renovations over the years. The Gulf Expressway is a 43,600-foot-long bridge that is one of the longest in the world. It connects the I-10 and I-45 freeways, making it a key transportation route between Houston and the Gulf Coast.
The Jubilee Parkway connects Blakely Island to Daphne in Alabama, providing a vital transportation link between these two important communities. The twin concrete viaducts each have two lanes, and the bridge spans a length of 7.5 miles (or 12.1 kilometers) across Mobile Bay. In addition, there is an interchange in between, with the Battleship Parkway which runs almost parallelly to this one.
The Jubilee Parkway was built in 1978 to help increase seafood availability in Mobile Bay and it is still in use today. It’s one of the longest bridges in the USA, and it’s a popular tourist destination due to its easy-to-catch seafood opportunities.
San Mateo-Hayward Bridge
The San Mateo-Hayward Bridge connects two beautiful parts of the Bay Area and is a crucial link between the Peninsula and the East Bay. This bridge is a beautiful example of engineering excellence, and it plays a vital role in connecting the two regions. This beautiful new bridge was built in 1960 and has lasted for more than 50 years. It’s a long 7-mile bridge with two lanes. It’s a great investment and has saved taxpayers a lot of money.
