One of the most popular photo spots with an excellent view of Frankfurt's skyline. This famous iron and concrete footbridge, crossed by over 10,000 pedestrians every day, connects the city centre and Römerberg with Sachsenhausen on the southern banks of the Main River. The neo-Gothic-style bridge was built in 1869 according to the plans of Peter Schmick, going through several changes and modifications since then, the last of which took place in 1993. https://www.frankfurt-tourismus.de/en/Discover-Experience/Best-of-Frankfurt2/Eiserner-Steg

Once called "the bridge that couldn't be built," today it is one the seven wonders of the modern world. This magnificent span, perhaps San Francisco's most famous landmark, opened in 1937 after a four-year struggle against relentless winds, fog, rock and treacherous tides. Crossing the strait of the Golden Gate from San Francisco's Presidio to the Marin headlands for 1.7 miles is the world-renowned Golden Gate Bridge, easily identified by its International Orange color. Opened in 1937, the bridge was built at a cost of $35 million in principal and $39 million in interest and 11 workers’ lives. The single-suspension span is anchored by twin towers that reach skyward 746 feet, and was once taller than any building in San Francisco. To support the suspended roadway, two cables, each more than 7,000 feet in length and both containing 80,000 miles of wire stretch over the top of the towers and are rooted in concrete anchorages on shore. More than 10 years in planning due to formidable opposition, but only four years in actual construction, the Golden Gate Bridge brought the communities of San Francisco and Marin counties closer together. http://www.sftravel.com/golden-gate-bridge

Prague’s oldest bridge was built to replace the Judith Bridge that had been badly damaged by floods in 1342. The Stone, or Prague, Bridge, called Charles Bridge since 1870, was begun in 1357 by Charles IV and was completed in 1402. The bridge is built of sandstone blocks, flanked at each end by fortified towers (Lesser Town Bridge Towers, Old Town Bridge Tower). From 1683 to 1928, 30 statues of saints were carved to decorate the bridge, the most famous of which is the statue of St John of Nepomuk. https://www.prague.eu/en/object/places/93/charles-bridge-karluv-most?back=1

Although it is only a 20th century creation, Palace Bridge is undoubtedly one of the most famous sights of St. Petersburg, and is quite literally unmissable for most visitors to the city, who will find themselves continually using the bridge to move between Palace Square, home to the Winter Palace and the Hermitage Museum, and the numerous historic attractions on Vasilevskiy Ostrov. Despite the grandeur and extravagance of the surrounding architecture, Palace Bridge itself is a relatively simple structure, comprising five cast-iron spans resting on granite-clad, packed-rubble piers. Height of the bridge was strictly limited, so as not to obstruct the view of the monuments around. The central span of the bridge splits into two wings, which are raised through an angle of over 45° to allow ships to pass up the Neva River, and the view of the golden spire of the Ss. Peter and Paul Cathedral between the two raised wings is one of the most widespread and memorable images of St. Petersburg. It also makes Palace Embankment the centre of nightly celebrations during the White Nights, when thousands of locals and visitors gather to watch Palace Bridge open in the small hours. http://www.saint-petersburg.com/bridges/unmissable-palace-bridge/
