The Hartland Covered Bridge is the longest-covered bridge in the world. Located in Canada, the Hartland Covered Bridge crosses the Saint John River. It connects Hartland to Somerville, New Brunswick.

While it only has one lane, the bridge offers a convenient route for passengers. Before its construction, the only way to cross the Saint John River was by ferry. Now, vehicles less than 13.8 feet tall can easily pass through the Hartland Covered Bridge.

The bridge holds a special place in the hearts of locals. Couples would often stop halfway across the bridge and share a kiss for good luck. In 1992, a happy couple even held their wedding on the bridge.

Ikitsuki Bridge

Total length: 0.24 miles

While the Ikitsuki Bridge isn’t the longest bridge in the world, it is the longest continuous truss bridge ever. A truss bridge refers to a type of bridge without hinges or joints on three or more of its supports.

Planning for the Ikitsuki Bridge began in 1983, and at the time, the only way to reach Ikitsuki was by ferry. In 1991, the construction finished, and the Ikitsuki Bridge opened to the public. This steel road bridge is 59 feet tall and around 21 feet wide. It connects Ikitsuki, Nagasaki to Hirado Island and allows vehicles to pass through.

Before the construction of the Quebec Bridge, there were only two ways to travel from St. Lawrence to Quebec City. Travelers could take the ferry or wait for the winter to freeze over the water and create an ice bridge.

In 1900, the construction of the Quebec Bridge to connect these two areas began. Unfortunately, the bridge collapsed twice in 1907 and 1916. These accidents didn’t just delay the construction. It also led to 88 deaths and several injuries. Finally, in 1919, the Quebec Bridge finally finished and opened. It now stands as a road, rail, and pedestrian bridge.

As the longest clear-span cantilever bridge in the world, the Quebec Bridge became a National Historic Site of Canada in 1995. It was also the first bridge in North America to use nickel steel.

Walkway over the Hudson

Total length: 1.28 miles

Also known as the “High Bridge”, the Walkway Over The Hudson is the world’s longest elevated pedestrian bridge in the world. This double-track railroad bridge spans the Hudson River, and it is a part of the Maybrook Railroad Line. It connects the east bank of Poughkeepsie, New York to the west bank of Highland, New York.

Unfortunately, it closed down in 1974 after a devastating fire damaged the railways. In 2009, the bridge re-opened as a pedestrian walkway. It became a part of the New York State Bridge Authority’s Walkway Over the Hudson State Historic Park.

In the same year, the American Society of Civil Engineers also honored the bridge as a National Historic Civil Engineering Landmark.

Evergreen Point Floating Bridge

Total length: 1.46 miles

The Evergreen Point Floating Bridge might not be the longest bridge in the world, but it holds another impressive title. According to the Guinness World Records, it is the longest floating bridge in the world.

The Evergreen Point Floating Bridge connects Seattle to its eastern suburbs by carrying the Washington State Route 520. Because of this, it is also called the 520 Bridge.

On April 2, 2016, the government of Washington celebrated its opening with around 40,000 attendees. The festivities included a ceremony, a fun run, and a community walk along the bridge. In 2017, the bridge received the 2017 Grand Conceptor Award.

Russky Bridge

Total length: 1.93 miles

Located in Russia, the Russky Bridge connects Russky Island and the Muravyov-Amursky Peninsula. It spans the Eastern Bosphorus strait at 230 feet above the water.

The Russky Bridge is the longest cable-stayed bridge in the world. It is a concrete and steel bridge with four lanes and a total width of 97 feet. The bridge’s initial purpose was to ease traffic for the 2012 Asia-Pacific Economic Cooperation Conference at the Far Eastern Federal University on Russky Island.

Thankfully, the bridge’s construction ended in July 2012. It opened to the public months ahead of the conference.

Akashi Kaikyō Bridge

Total length: 2.43 miles

Longest Bridge in the World: Akashi Kaikyo Bridge

The Akashi Kaikyo Bridge is a suspension bridge in Japan. Construction of the bridge began in 1988, and it ended after a decade in 1998.

Despite its impressive length, the Akashi Kaikyo Bridge isn’t the longest bridge in the world. However, it is a crucial link in the Honshu-Shikoku Bridge Project. The bridge crosses the Akashi Strait and connects Kobe City on Honshu to Iwaya on Awaji Island.

The Akashi Kaikyo Bridge is also a popular tourist attraction. Tourists can avail of a tour that lets them walk down part of the bridge. They can even go up to one of the main towers on the bridge. At the top of the 948-feet tower, tourists can enjoy an amazing view of Japan.

1915 Canakkale Bridge

Total length: 2.86 miles

While the Sky Bridge 721 is the longest suspension footbridge ever, the 1915 Canakkale Bridge is the longest suspension bridge in the world. The 1915 Canakkale Bridge is only open to vehicles and not pedestrians.

Despite its name, the Canakkale Bridge isn’t actually from the 1900s. Its construction began in March 2017, and it ended recently on February 18, 2022. The “1915” in its name honors an important event in the history of Turkey. In 1915, the Ottoman Empire’s navy won against the United Kingdom and France’s navy during World War I.

Öland Bridge

Total length: 3.77 miles

The Oland Bridge connects the city of Kalmar on Sweden’s mainland to the island of Osland. It opened on September 30, 1972, as a road bridge for vehicles. It is 42 feet wide and has four lanes.

There are 156 pillars that support the bridge, and it also has a distinct hump on its western end. This hump was intentional as it provides ships with a vertical clearance of around 118 feet.

The Oland Bridge was the longest bridge in Europe until the Oresund Bridge opened in 1998. While it might have lost this title, the Oland Bridge remains the longest bridge in Swedish territory.

Mackinac Bridge

Total length: 4.99 miles

As its name suggests, the Mackinac Bridge spans the Straits of Mackinac. This suspension bridge connects Upper Michigan and Lower Michigan.

The Mackinac Bridge opened to the public on November 1, 1957. Before that, however, tragedy struck. Five workers died while construction was ongoing, and many believe their bodies were buried in the concrete. Of course, this is only a myth. A plaque by the bridge’s northern end honors the five men.

Unfortunately, this wasn’t the only misfortune to occur on the bridge. On September 10, 1978, a private plane smashed into the bridge’s suspension cables. Three U.S. Marine Corps Reserve officers were on board, and they all died as the plane fell into the Straits of Mackinac.

The Mackinac Bridge is among the longest bridges in the world. With a main span of 3,800 feet, it is also the third longest suspension span in the United States.

One of the longest bridges in the world is the 6th October Bridge. You can find the 6th October Bridge in Cairo, Egypt, where it crosses the Nile River twice. It connects Gezira Island and Downtown Cairo to the Cairo International Airport.

The name, “6th October Bridge”, references the date when the Yom Kippur War began. On October 6, 1973, the Egyptian military executed Operation Badr, where soldiers crossed the Suez Canal.

Locals also call the bridge the “Spinal Cord of Cairo”. Because of its location, the elevated highway is Cairo’s major route for East-West travel. Around half a million Cairenes use the highway every day. This also means the bridge often has congested traffic. A single trip across the bridge will probably take around 45 minutes.
