Avenida 9 de Julio in Buenos Aires, Argentina, holds the Guinness Record for the widest avenue in the world, at approximately 140 meters. It features a total of 16 lanes, so crossing from one side to the other is quite an undertaking.

The history of Avenida 9 de Julio can be traced back to the glory days of the Argentinian capital. Buenos Aires was called the ‘Paris of South America’, so local authorities decided to cement that reputation by building a monumental piece of infrastructure inspired by Paris’ Champs Elysee. Only a simple copy wasn’t enough they wanted something larger, more impressive, so they settled on an urban highway passing through the center of the city that was double the width of the famous French avenue. It was a colossal project that took almost half a century to finish, but in 1980, Avenida 9 de Julio was finally completed. It still holds the record for ‘world’s widest avenue’.

Switzerland’s road maintenance authority has developed an ingenious mobile bridge that allows the paving of public roads without the need to stop traffic on the affected lanes.

Traffic jams are a necessary evil when it comes to road maintenance, and despite experts’ best efforts to come up with a solution to this logistic problem, motorists still have to deal with them whenever road work is required. However, Switzerland’s Federal Roads Office may have come up with an ingenious-enough solution to revolutionize road paving. Earlier this year, it unveiled the Astra Bridge, a 257-meter-long mobile bridge that allows traffic to pass over sections of road while infrastructure is being repaired below. It’s such a simple concept that it almost makes you wonder why engineers took so long to invent it, but there is a reason why the Astra Bridge is the first of its kind – it’s not as simple as it sounds.

A 149-mile-long stretch of highway connecting two towns in Saudi Arabia holds the title of the world’s longest straight road.

Saudi Arabia’s Highway 10 stretches 916 miles (1,474 km), connecting the town of Al Darb, in the southwest, to Al Batha, in the east. It’s quite a busy road, most traversed by trucks shipping goods from one side of the country to the other, but it is most famous for a 149-mile stretch through the Rub-al-Khali desert. This particular piece of infrastructure was originally built as a private road for King Fahd (SAU), but ever since it became part of the public road system, it claimed the Guinness Record for the world’s longest straight road, also known as ‘the most boring road in the world’, due to its complete lack of bends, almost completely flat terrain, and bland, featureless surroundings as far as the eye can see.

The Putrajaya Roundabout in the administrative capital of Malaysia holds the Guinness record for the world’s largest roundabout. It measures 3.4km in circumference and features 15 entry/exit points.

Located in the heart of Putrajaya, the administrative capital of Malaysia, the Persiaran Sultan Salahuddin Abdul Aziz Shah Roundabout, aka Putrajaya Roundabout, is one of the most unusual attractions in the Southeast Asian country. It was designed by renowned Malaysian architect Hijjas Kasturi and inaugurated in 2003. A feat of modern infrastructure engineering, the world’s largest roundabout is built around Istana Melawati, the second-largest palace of Malaysia’s Yang di-Pertuan Agong, the Putra Perdana Landmark, and a luxurious five-star hotel. It is also the main access point to Putrajaya’s major attractions, including the prime minister’s green-domed office complex and the city’s enormous mosque.

Locals in the Indian state of Maharashtra were shocked to discover that their newly-laid road was actually just a carpet with a thin layer of asphalt poured over it.

According to the Lokmat Times, the people of Karjat-Hast Pokhari, a village in Maharashtra’s Jalna district, had long been pleading with elected representatives to rebuild their poor roads, and last month, their prayers were finally answered. Or, at least, that’s what they originally thought when they saw the layer of asphalt covering their dirt roads. Only their joy was short-lived, as it soon became clear that the company in charge of the project did a very shady job, laying a very thin layer of asphalt over a carpet-like canvas that could easily be lifted from the dirt base with little effort.

In early 2021 Saudi Arabia’s Crown Prince unveiled the concept of a futuristic urban development called The Line, which basically consists of a linear, 170-km-long city without roads of cars and built around nature.

During his presentation of The Line, back in January, Prince Mohammed Bin Salman described the future smart city as a direct response to growing challenges like human congestion, pollution, traffic and outdated infrastructure. Linking the coast of the Red Sea with the mountains and upper valleys of the north-west of Saudi Arabia, The Line will be powered by Artificial Intelligence (AI), continuously learning predictive ways to make life easier for both residents and local businesses. It will be powered by 100% clean energy and will feature an underground hyper-speed transportation system, instead of roads and cars.

A giant puddle in Russia’s Far East city of Yuzhno-Sakhalinsk is being described as “invincible”, after it somehow survived unfixed for over a quarter of a century. It now has its own Instagram page and over 16,000 followers.

As it often happens in Russia and other eastern European countries, what started out as a small pothole gradually grew to become a giant puddle. It attained that rank in 1994, and locals have been trying to get local authorities to fix it ever since. So far it has proven a futile endeavor, as scheduled repairs have been postponed repeatedly. In the meantime, a frustrated local known only as Nikolay decided that the 25-year-old pothole was old enough to have its own Instagram page, and created one for it in September. The witty sarcastic posts created in first-person quickly went viral and got the local government to act.

Authorities in Cairo, Egypt, have come under fire for approving the construction of an “essential” highway bridge literally half a meter from several apartment buildings.

Egyptian social media has been abuzz over a new high-speed bridge currently under construction in Cairo’s Al-Haram district, for the simple reason that it is being built right next to a number f residential buildings on Nasr El-Din Street. And when we say “right next to”,  we mean that in the most literal sense, as the bridge is just 50 centimetres away from people’s homes. However, in a surprising twist, authorities announced that the bridge had all the necessary permits, and that it was the residential buildings that had been built without a permit. Therefore, an order for their demolition has already been issued.

A 45-year-old man from rural Kenya is being hailed a hero by his community after single-handedly digging a one-mile road through a bushy area in oly six days, using only rudimentary tools.

The people of Kaganda, a small village 80km north of the Kenyan capital, Nairobi, had long been appealing to local government officials to start work on a short stretch of road that would shorten their daily trips to a nearby shopping center. Although the bushy area on which the road was supposed to be built had been earmarked by authorities, local leaders kept stalling the project. After a shorter footpath that Kaganda villagers used to get to the shopping center was fenced off because it passed through private property, the people were left with no option but to walk 4km every day. That’s when a local hero decided to take matters into his own hand and dig the much-awaited road himself, for free.

China is famous for its bewildering and oftentimes confusing highway interchanges, but the Qianchun interchange in the mountainous province of Guizhou is the only one that actually looks like a giant rollercoaster for cars and trucks.

Construction on the Qianchun Interchange began in 2009, but the massive road knot was only completed last year . It consists of 18 different ramps, in 8 directions, on five different layers, with the highest one standing 37 meters above ground. Like the nearby Huangjuewan Overpass, in Chongqing, this incredibly complex infrastructure project has been labelled a nightmare for motorists trying to find their way around.

Officials in the Primorski district of Saint Petersburg, in Russia, apparently decided it would be cheaper to hire a good graphic designer to touch up some photos of damaged infrastructure than actually fixing it.

According to a news story that went viral on Russian social media a few days ago, the local administration of Primorski district recently reported the completion of repairs on a pedestrian walkway, and even posted photos of the pristine-looking footpath on its official website, as proof. The photos look legit to the untrained eye, but they quickly drew the attention of locals who knew for a fact that the walkway was still in a poor state and no repairs had been conducted on it for years. They took some photos of the actual footpath and uploaded them on social media, accusing local authorities of trying to deceive the public.

Cycling enthusiasts in Lidzbark Warminski, a small town in Northern Poland, have recently received a unique, awesome present from the local authorities – a brand new sun-powered bicycle path that glows bright blue all night long.

Scientists at Polish construction company TPA Instytut Badan Technicznych in Pruszkow created the innovative 100-meter bicycle path using luminophores, a synthetic material that lights up when charged with sunlight. According to TPA president Igor Ruttmar, “The material we used for the track gives light for over ten hours. That means the road can radiate throughout the whole night and reaccumulate light the following day”. Apparently, the new material can emit light in a variety of colors, but designers chose blue because it went well with the surroundings in Lidzbark Warminski.

Topmix Permeable is a new type of super-absorbent concrete designed to soak up nearly 900 gallons of water in only one minute! Streets paved with this special, ‘thirsty’ concrete will not flood during storms, and they’ll also remain free of puddles and potholes.

Lafarge Tarmac, the company that developed the technology, uses relatively large pebbles to make a permeable top layer of concrete. Water that hits the surface will seep through the matrix into a loose base of rubble underneath. Drainage channels are worked into the rubble, to help increase the amount of water absorbed.

Meet Gangadhara Tilak Katnam, the man who single-handedly fixed over 1,000 potholes in his hometown of Hyderabad, India. The 66-year-old pensioner has made it his mission to fix the city’s roads, earning himself the nickname ‘road doctor’.

Since 2011, the former railway engineer has been driving around the city every single day, looking for abandoned tar and gravel on roadsides. He collects the unclaimed material and uses it to fill potholes, at times spending his own pension money to do it. Tilak, who calls his work ‘Shramadaan’ (offering physical help), doesn’t confine himself to his neighborhood – he patches up every pothole he can find in the city.

“After working for the South Central Railway for 35 years, I retired in October 2008 and spent some time off in 2009, also traveling to the US to meet my son,” Tilak told the local media. “In January 2010, I came back and settled down in Hydershakote, in Hyderabad and took up a job as a consultant in a software agency.” It was during the course of commuting to this job that Tilak found his calling.

The city of Trondheim in Norway is the first and only one in the world to have a lift specially designed to help cyclists travel uphill. The contraption is called ‘Trampe’ and it can get you up a very steep hill with practically no effort on your part.

Trampe was first opened in 1993, and quickly turned Trondheim into a very popular tourist destination for cyclists. Over 200,000 cyclists have used it to go up a 130-meter hill, with no accidents reported so far. In 2012, the original lift was dismantled and replaced with a more industrialized version in 2013, called the CycloCable.
