Locale: Florence, Italy | Crosses: Arno River
Design: Closed-Spandrel segmental stone arch bridge
Width: 32m (105ft) | Longest span: 30m (98ft)

Ponte Vecchio (which means "Old Bridge") in Florence is one of the famous tourist attractions in Italy, and is considered the oldest stone arch bridge in Europe. Even the bridge itself is older. Actually built from wood until it was destroyed by floods in 1333, and twelve years later the bridge was rebuilt using stone.
Famous for its many shops, the bridge is also a home for everyone from traders and butchers to the gift shop and art sales from the Middle Ages.

02. Ponte Sant'Angelo, Rome, Italy
Ponte Sant'Angelo, Italy

Locale: Rome, Italy | Crosses: Tiber
Design: Arch bridge | Material: Stone
Carries: Pedestrian | Longest span: 18m

Ponte Sant’Angelo spanning the Tiber in Rome, one of the eight stone bridges the Romans are known to have built over the Tiber between 200 B.C. and A.D. 260, is the most celebrated of the six “massive beauties” still in use, said Judith Dupré, author of Bridges.
“The Romans perfected the masonry arch,” she said, allowing them to span much greater distances than previously. “Much of Roman engineering genius is underwater, hidden from view, but their inventions—including the cofferdam, cutwater piers that divide water current, and pozzolano, a type of waterproof concrete—are still used today,” Dupré said.
Ponte Sant’ Angelo, originally named for Hadrian, the emperor who reigned during its construction, leads to his mausoleum, Castel Sant’ Angelo, a popular tourist attraction in Rome.

03. Lonardo's "Golden Horn" Bridge, Norway

Locale: Oslo, Norway | Architect: Vebjørn Sand

Designed in 1502 by Leonardo da Vinci to span the “Golden Horn,” the famous waterway in Istanbul that separates Europe and Asia, the stone bridge was never built because the Turkish sultan feared that it was not technically feasible. A scaled down, laminated wood and stainless steel version based on the famous artist’s original plan is now a footbridge near Oslo, Norway.
“For 500 years the beauty and symbolism of this graceful bridge remained an obscure drawing in one of Leonardo’s notebooks, until it was brought into being in Norway in 2001 by the contemporary artist Vebjorn Sand,” according to the website of The Leonardo Bridge Project, a global public arts project.
Built in collaboration with the Norwegian transportation ministry, the bridge was the first civil engineering idea by Leonardo to be realized.

Locale: Cornish, New Hampshire to Windsor, Vermon | Cost: $9000
Design: Town lattice truss bridge | Material: Wood
Length: 137m (449ft 5in) | Longest span: 62.2m (204ft)

The Cornish-Windsor Covered Bridge, built in 1866, crosses the Connecticut River between New Hampshire and Vermont. Cited as the longest two –lane covered bridge in America, it is on the National Register of Historic Places. The bridges were covered to protect the structures from snow, ice, and rain and ensure their longevity. But due to wood’s vulnerably to fire, floods, and other natural disasters, and with the advent of cars and highways, few remain today. By the mid 50's, there were less than two thousand left, according to Dupré.

05. Brooklyn Bridge, New York, USA

Length: 1825 m (5989 ft) | Longest span: 486.3m (1595ft 6in)
Carries: Motor vehicles, Elivated trains, Street cars, Pedestrian, Bicycle

Few bridges are as iconic as New York’s beloved Brooklyn Bridge, which spans the East River and connects Manhattan and Brooklyn. Among the world’s first wire cable suspension bridges, it established a number of engineering precedents, according to the National Park Service, which designated the bridge a National Historic Landmark.
The bridge was conceived in 1855 by John Roebling (who died before ground was broken), and work was carried out first by Roebling’s son, and later by his daughter-in-law. The Brooklyn Bridge is a quintessential American landmark. Since opening day in 1883, it “has tugged on the human heart for as many reasons as there are hearts.”

06.Magdeburg Water Bridge, Magdeburg, Germany

Locale: Magdeburg, near Berlin| Crosses: River Elbe
Water Depth: 4.25m | Longest span: 106m
Length: 918 m (690 m over land and 228 m over water)

On September 9, 2008, the Banpo Bridge in Seoul (South Korea) got a major facelift: a 10,000-nozzle fountain that runs all the way on both sides. Immediately after being installed, the bridge turned into a major tourist attraction, as the bridge pumps out 190 tons of water per minute using the water from the river below.
6 years, 500 million euros, 918 meters long.......now this is engineering! This is a channel-bridge over the River Elbe and joins the former East and West Germany, as part of the unification project. It is located in the city of Magdeburg, near Berlin. Taking six years to build and costing around half a billion euros, the massive undertaking will connect Berlin's inland harbor with the ports along the Rhine river. At the center of the project is Europe's longest water bridge measuring in just shy of a kilometer at 918 meters. The huge tub to transport ships over the Elbe took 24,000 metric tons of steel and 68,000 cubic meters of concrete to build. The water bridge will enable river barges to avoid a lengthy and sometimes unreliable passage along the Elbe. Shipping can often come to a halt on the stretch if the river's water mark falls to unacceptably low levels.

Last but not least, moving yet further east around the globe, we reach a humble walking bridge in Redding, California. The stylish Sundial Bridge across the Sacramento River is a glass-bottom bridge that connects a network of walking and biking trails. The requirement before planning the bridge was that it could not cast too much shadow over the river as Turtle Bay happens to be one of the best salmon spawning places in California. Therefore, the design is light and airy. Opened in July 2004, the bridge’s construction cost €17.4 million.

While it may provide picturesque views of the valley below, once the mist descends it is not a route for the faint hearted! The deck is lofted on 7 pylons and weighs 36,000 tonnes. A series of 7 masts, each 292-ft tall and weighing 700 tonnes, are attached to the corresponding pylons.

Nearly 450,000 tons of steel was used in its construction along with 2.3 million cubic meters of concrete. Chinese officials said the bridge was designed to be strong enough to withstand a magnitude 8 earthquake, typhoons, or the impact of a 300,000-ton vessel. China is already home to seven of the world’s 10 longest bridges, including the lengthiest – the 102 mile Danyang-Kunshan rail bridge near Shanghai, which runs over land and water.

Rolling Bridge, UK
Rolling Bridge

Designed by Heatherwick Studio, the award-winning Rolling Bridge is located Paddington Basin, London. Rather than a conventional opening bridge mechanism, consisting of a single rigid element that lifts to let boats pass, the Rolling Bridge gets out of the way by curling up until its two ends touch. While in its horizontal position, the bridge is a normal, inconspicuous steel and timber footbridge; fully open, it forms a circle on one bank of the water that bears little resemblance to its former self.
12m long, the bridge is made in eight steel and timber sections, and is made to curl by hydraulic rams set into the handrail between each section.
