Highway 10 is a highway in Saudi Arabia, stretching from Ad Darb in Al Darb Governorate to the SaudiâÂÂUAE border near the Persian Gulf. The highway is long.
The highway became famous for its straight section that is long between Haradh and Al Batha, and has no bends or noticeable gradients, earning it the world record for the longest straight road.
The straight section of Saudi Arabia's Highway 10 has emerged as the world's longest straight road, surpassing the straight section of Australia's Eyre Highway.
The highway cuts through the vast Rub' al Khali desert, also known as the Empty Quarter. The road was originally built as a private road for King Fahd of Saudi Arabia.
