World's Longest Road Passes Through 14 Countries, No U-Turn For 30,600km
The Pan-American Highway, the world's longest motorable road at 30,600 km, runs from Prudhoe Bay, Alaska to Ushuaia, Argentina, crossing 14 countries. It opened by 1960
While India's National Highway 44 holds the distinction of being the longest road in the country, spanning a remarkable 4,112 kilometres, on the global stage, an even more extraordinary roadway takes the spotlight.
Stretching an astonishing 30,600 kilometres (19,000 miles), the Pan-American Highway is the longest motorable road in the world. Traversing the vast expanse of the American continents, it begins at Prudhoe Bay in Alaska and ends at Ushuaia in Argentina, at the southernmost tip of South America. What makes this route particularly unique is that it cuts across 14 countries without requiring a single U-turn.
A Monumental Feat Of Engineering
Originally conceived in the early 1920s to promote tourism and connectivity across the Americas, the Pan-American Highway is a testament to international cooperation. By 1937, all 14 participating nations had committed to the project, and the route was officially opened to traffic by 1960.
The 14 countries along its path include Canada, the United States, Mexico, Guatemala, El Salvador, Honduras, Nicaragua, Costa Rica, Panama, Colombia, Ecuador, Peru, Chile, and Argentina. Each nation is responsible for the maintenance of the portion of the highway that runs through its territory.
More Than Just A Road
Beyond its sheer length, the Pan-American Highway offers travellers a captivating journey through some of the world's most diverse landscapes. From snow-covered mountains and arid deserts to lush forests and sweeping coastlines, the route presents an ever-changing tableau of natural beauty.
Travelling this road at a pace of 500 kilometres per day would still require over two months to complete the full journey. Its straight path, devoid of sharp turns or detours, makes it not just the longest but arguably one of the straightest highways in existence.
The Pan-American Highway is more than just a marvel of infrastructure, it is a cultural corridor, linking nations and communities with shared histories, economic ties, and a spirit of cooperation that has endured for over a century.

Inside America's Long Tieng: The Most Secret Nerve Centre Of A Covert CIA Operation
Far from tourist trails and modern highways in Laos lies a forgotten piece of Cold War history. A cracked airstrip cuts through the green hills of Long Tieng, a village that, five decades ago, was ground zero for a covert U.S. operation that ran parallel to the Vietnam War. Today, Long Tieng, according to CNN, looks like any other rural settlement in Southeast Asia. A few guesthouses, basic shops and farming plots line the road. Children ride scooters across what used to be a military runway. Most residents work the land. Few of them have ever flown on a plane. Even fewer realise that this valley was once considered 'the most secret place on Earth'. From the early 1960s to 1975, Long Tieng served as the headquarters of a clandestine war effort backed by the U.S. Central Intelligence Agency (CIA). The goal was to block the spread of communism across Southeast Asia, specifically in Laos, where American forces were officially barred from operating under international agreements. The CIA partnered with the Hmong ethnic minority, led by General Vang Pao, to build a paramilitary base in the village. The site rapidly grew into a military hub. At its peak, over 30,000 people, including Hmong fighters, their families, Thai soldiers, American agents and CIA-linked pilots, lived and worked here. Roughly 4,500 feet long, the CNN report says, the airstrip handled up to 900 take-offs and landings each day. Supplies such as ammunition, food and fuel were flown in by aircraft operated by Air America, a CIA-owned airline. Smaller planes then distributed these resources to remote outposts across the region. Pilots known as 'Ravens' operated from the site as well. These U.S. Air Force personnel flew low-level missions to identify targets and direct bombing runs. Many of them worked in civilian clothing under diplomatic cover, blurring the line between soldier and spy. Despite its size and significance, the report suggests, Long Tieng remained unknown to much of the outside world. Even U.S. troops fighting in neighboring Vietnam were unaware of the base. Secrecy was absolute. After the U.S. withdrew in 1975 and the Pathet Lao took power, Long Tieng emptied out almost overnight. Thousands of Hmong were displaced. The site was abandoned. What remains now are skeletal buildings, overgrown runways and rusting equipment. Many of the bunkers and hangars have collapsed. Today, reaching Long Tieng is still difficult. The journey from Vientiane takes more than eight hours. Roads are unpaved, narrow and often blocked by landslides or mining trucks. Communication is limited, and phone signals are unreliable in the mountains. Despite its history, the site sees very few visitors. A handful of local tour operators organise occasional trips, but there are no museums, no signs and no official preservation efforts. General Vang Pao's former headquarters still stands. A plain two-story house, now empty, with a 'no entry without permission' sign posted in English. Visitors who make it inside find little more than a wooden desk, artillery shells stacked in a corner and a view of the now-silent airstrip. The legacy of the conflict continues to affect Laos. According to the Mines Advisory Group (MAG), roughly 80 million unexploded submunitions remain scattered across the countryside. Villagers in the Long Tieng area still avoid walking off known trails for fear of triggering dormant explosives. Since 1995, the United States has invested nearly $400 million to support weapons clearance programs in Laos. Still, progress is slow, and fears about future funding cuts continue to raise concerns. For many in Long Tieng, life has returned to a quiet rhythm. Children play where warplanes once launched. Farmers plant rice on land that once held military barracks. But for those who know the history, the scars remain visible and buried. The war may have ended 50 years ago, but its echoes still shape this hidden valley.

Post Pahalgam attack, anti-terror squad deployed for 1st time at Valley of Flowers
1 2 3 4 Dehradun: Uttarakhand Police has deployed a six-member anti-terror squad (ATS) team at Ghangaria, near the Valley of Flowers, to monitor tourist movement towards the alpine valley as well as popular Sikh pilgrimage spot, Hemkund Sahib, situated nearby, marking the first time such a deployment has taken place in this remote region. The decision is being seen as linked to the Pahalgam terror attack on April 22 that left 25 tourists and a local dead. Chamoli SP Sarvesh Panwar, told TOI, "The ATS team has been stationed at Ghangaria, the key point for people going to both Valley of Flowers and Hemkund Sahib. The ATS team has been stationed there since May 24, a day before the Hemkund Sahib yatra began, and will work alongside the State Disaster Response Force to ensure the smooth and safe conduct of the pilgrimage and tourist traffic." According to sources, ATS deployment is part of a wider security strategy across Uttarakhand, which shares its border with China, in response to the Pahalgam incident in Jammu & Kashmir. While officials have not cited any direct threat or intelligence input linked to Chamoli district (where the Valley of Flowers lies, and which shares borders with China), police have increased surveillance across major tourist and religious sites in the Himalayan state as a precaution.

Also, police have been monitoring social media and providing support to around 1,700 Kashmiri students in Uttarakhand to maintain public order and prevent misinformation. The Valley of Flowers National Park, a Unesco World Heritage site, reopened to tourists on June 1. Located over 9,000 ft above sea level in Chamoli, the park remains open from June to Oct and is known for its alpine flora. On opening day, 83 visitors visited the valley. Declared a national park in 1982, it is home to over 600 plant species, including Brahma Kamal, the state flower of Uttarakhand, along with Aster, Delphinium, Himalayan Blue Poppy, Ranunculus and Potentilla. Hemkund Sahib, the revered Sikh shrine situated nearby, opened to devotees on May 25 and draws thousands of pilgrims every year.

It's getting harder and pricier to fly with your pet
Flying with your pet this summer? Better brush up on confusing rules and higher fees. Oh, and have a plan B ready in case things go awry at the airport. Christina and Michael Kutzner spent hours boning up on the regulations so she could travel with her mother's dog from Las Vegas to Detroit in first class in April. They called Delta, tested different pet carriers, scoured online forums about in-cabin pet travel and more. It wasn't enough. The 20-pound dog was turned away at the airport for being too tall for an under-the-seat pet carrier. Christina and her mom had to buy expensive, last-minute tickets on American for the next day. Christina Kutzner and her mother were told that Kona was too tall for their pet carrier. They also had to get a new crate so Kona, a Shiba Inu, could fly in cargo. (Delta no longer takes pets in cargo except for certain active military or State Department employees.) And they had to fly into Chicago instead of Detroit and rent a car. It was, they say, an expensive lesson. 'We just want to make sure that people are aware there's not a lot of good information out there,'' Michael Kutzner says. Traveling with pets has never been simple. And it has become more difficult and expensive since U.S. airlines, with the support of the Transportation Department, banned emotional-support animals in 2021 after a surge in incidents. The only animals allowed in the cabin now are service animals with proper documentation and small pets in approved carriers that fit under a seat. The list of rules and regulations to bring your cat or small dog on the plane reads like the fine print on a basic economy ticket. It's even worse if you're traveling internationally. Figuring out whether that carry-on bag will pass muster in the airline bag-sizer is a cinch compared with whether your pet carrier and its beloved occupant will be cleared to fly with you. Airlines have robust pet sections on their websites but deciphering them isn't always easy, especially for newbies. Delta's website, for example, states that in-cabin pets must be 'small enough to fit comfortably in a kennel with the ability to move around without touching or sticking out from the sides." American's says only that the pets must be 'small enough to fit comfortably inside the closed/zipped carrier." The rules keep changing, too. Alaska Airlines last week said it would no longer allow passengers to book a separate seat for their pet. It was the last U.S. airline to offer the option of buying a second seat for a dog crate. It was popular with owners of medium-size dogs too big to fit under the seat. Other airlines that let you buy a second seat for a pet don't let you put the carrier on the seat. Thanks to Signature Pet Transport, a Petit Basset Griffon Vendeen named Rooney was delivered from his breeder to his new family. Supporters have filed a petition to reverse the decision. The airline also decreased the eligible carrier size for under-seat pets and said it would no longer take birds and rabbits beginning next year. (Alaska says it and other changes are designed to align its policies with those of merger partner Hawaiian Airlines.) Another challenge for travelers: Pet fees can now cost more than your plane ticket. A friend texted me last week lamenting the $300 price tag to bring her dog on a United flight from Denver to South Dakota. Her own ticket cost $209. American and United raised their domestic pet fees to $150 one way last year. Delta, which previously charged $95, joined the $150 club in April. JetBlue and Southwest charge $125 each way, Alaska $100. Cargo prices are higher. (It's all still cheaper than sharing a private charter or flying the new BARK Air—a luxury charter service for dogs, with prices starting at $6,000 one way for a pet and its human from New York to Los Angeles in July.) Even professionals find it hard to stay ahead of the varying pet policies and prices on airlines. 'We do our best to keep up with all of it," says Christian Diaz. The former flight attendant founded Signature Pet Transport in San Diego, which provides a variety of services—from phone consultation to guardians who travel with your pet—to help travelers navigate pet transport. Diaz, who is a regular contributor to the popular Flying with Dogs Facebook group, can rattle off airlines with what he considers the most generous under-seat carrier sizes (Delta tops the list domestically) and those with the stingiest (Hawaiian, American and now Alaska). Then there are the differences between a 20-pound French bulldog and a 20-pound Italian greyhound when it comes to fitting into a regulation-size carrier. The short, compact bulldog won't occupy much space, he says, but the greyhound has longer legs and probably won't make the airlines' cut, says Diaz who also breeds dogs and shows them. Diaz offers the following tips to reduce the chance of problems at the airport. Long before the day of travel, make sure the dog fits in the carrier and is comfortable. Practice, practice, take a chance if you think the dog is on the bubble sizewise. (Google any airline's pet policy and one of the related searches is always 'How strict is this airline?")Print out or bookmark the airline's policies and bring them with you. Airline employee understanding and enforcement of the complex rules can vary from flight to flight, airport to have a backup plan. The Kutzners story had a happy ending on American, but they wished they had received better directions from Delta throughout the process. Delta apologized for any miscommunication and says its pet policies are designed for 'safety and comfort throughout all aspects of flight." Write to Dawn Gilbertson at
