It is a continuous steel truss arch bridge with tie girders, and has a main span of 552 m. It is a real workhorse, carrying six lanes of traffic and two pedestrian walkways on its upper deck, and two light rail lines and four vehicular lanes on its lower deck. It was designed by the design institute of China Railway Major Bridge Engineering Group and the Chongqing Communications Research & Design Institute. It was built by the China Communications 2nd Navigational Bureau 2nd Engineering Co., Ltd., and completed in 2009.

It carries six lanes of the North-South Elevated Road, which intersects with the Inner Ring Road on the Puxi side of the river. It was designed by the Shanghai Municipal Engineering Design Institute, and built by the Shanghai Foundation Engineering Co. of the Shanghai Construction Group. It was completed in 2003. It is a popular tourist attraction. Visitors ride an elevator from the bridge’s base to the deck, and then climb 327 steps along the arch to an observation deck.

3. Bosideng Bridge, 530-m main span, China.

4. New River Gorge Bridge, 518-m main span, West Virginia. 

The New River Gorge Bridge is a steel arch bridge over the New River Gorge near Fayetteville. Completed in 1977, it was the world’s longest single-span arch bridge until 2003. The deck is 876 ft above the New River. It was the highest vehicular bridge in the world when it opened, and is currently the third-highest in the U.S. It was designed the Michael Baker Co. and built by U.S. Steel’s American Bridge division. It is made of Cor-Ten steel, a variety of steel alloy that was developed to resist corrosion and avoid the need for painting.

5. Bayonne Bridge, 510-m main span, New York-New Jersey. 

A steel arch bridge, the Bayonne Bridge links Bayonne, N.J., with Staten Island, N.Y. It was designed by noted bridge designer Othmar Ammann and architect Cass Gilbert, and opened in 1931. It spans the Kill Van Kull, a tidal strait connecting Newark Bay with Upper New York Bay, which is the main entryway for container ships destined for Port Newark. In order to accommodate larger post-Panamax ships that will be using the newly expanded Panama Canal, the Port of New York and New Jersey, the bridge’s owner, is raising the bridge’s roadway by 64 ft. A joint venture of Skanska Koch and Kiewit Infrastructure Co. were awarded a $743 million contract, and work began in 2013. A new roadway will be built above the existing road within the current arch structure, after which the existing roadway will be demolished. The project is expected to be completed in the summer of 2016.

Sixteen construction workers died during the building of the bridge. Tourists are allowed to ascend 200 steps to the top of the bridge’s southeast pylon. Paul Hogan worked as a rigger on the bridge’s maintenance staff for several years. He stumbled into show business when his workmates dared him to enter a TV talent contest in 1972. After stints as a comedian in clubs and TV, he boomed as Crocodile Dundee in 1986
