Imagine driving for more than two hours without turning the steering wheel even a single degree. No curves, no noticeable slopes, and no changes on the horizon. This is the reality of Highway 10<\/a> in Saudi Arabia, which holds the Guinness record as the longest straight road on the planet, stretching a completely linear distance of 240 kilometers.<\/p>\n Highway 10 stretches an impressive 1,480 kilometers from Ad Darb to the border with the United Arab Emirates. However, its most renowned segment is the portion between Haradh and Al Batha, originally built as a private roadway for King Fahd of Saudi Arabia. Today, this stretch serves as a vital artery for transporting goods between the central and western regions of Saudi Arabia and the Emirates.<\/p>\n The road crosses the Rub’ al Khali, also known as the Empty Quarter, the largest sand desert in the world. This vast area clarifies why such a straight road can exist: there are no mountains to navigate, valleys to cross, or geographical features to avoid\u2014just endless sand as far as the eye can see. The highway infrastructure is entirely paved, featuring two lanes in each direction, crucial for accommodating the intense truck traffic that traverses this arid environment.<\/p>\n<\/p>\n While passenger cars can reach speeds of up to 120 km\/h in the faster sections, buses are limited to 100 km\/h, and trucks face a speed cap of 80 km\/h. Although there were announcements in 2018 regarding the possibility of allowing light vehicles to speed up to 140 km\/h in specific areas, the reality of heavy truck traffic complicates maintaining higher speeds.<\/p>\n Driving on the world\u2019s straightest road is not as easy as it sounds, particularly due to fatigue. The desert’s monotonous landscape and absence of visual diversity can induce drowsiness and create a dangerous state of mind. The occasional presence of camels wandering across the road adds another layer of risk to this already challenging driving experience. It\u2019s no wonder this highway is featured on the Dangerous Roads website<\/a>.<\/p>\n Recognizing the hazards associated with such a monotonous driving environment, the Saudi Ministry of Transport and Logistics has implemented various safety enhancements. These include paved shoulders, reflective pavement markings (known as “cat’s eyes”), protective barriers, kilometer markers, and directional warnings. Vigilance is critical for drivers navigating a landscape with so few changes.<\/p>\n Before Highway 10 took the crown, Australia’s Eyre Highway<\/a> was known for its 146-kilometer straight stretch through the Nullarbor Desert. While shorter, this Australian road remains one of the continent’s most distinctive driving experiences. Other notable straight roads include North Dakota’s ND-46<\/a> and Argentina’s Route 40<\/a>, which, although not as long or straight, provide their own unique sense of visual monotony.<\/p>\n Driving on Highway 10 offers a unique experience\u2014mesmerizing yet mentally taxing. Its straight, endless stretch through the Empty Quarter complements the challenges presented by heavy traffic and a lack of visual stimuli. For those adventurous enough to undertake the journey, it promises both a sense of exhilaration and a reminder of the importance of vigilance on the road. <\/p>\n Cover image | City Vibes<\/a><\/p>\nA Highway Born for a King<\/h3>\n
