#17: Macau and Mainland China
At the Macau-Mainland China border, a fascinating road system exists. Drivers switch from left to right and vice versa via a looping road, reflecting the unique driving orientations of both regions. This 0.21-mile land and 24-mile coastal border showcases an inventive crossover solution.
The peculiar looped road configuration at the border is not just a curiosity—it’s a practical solution for smooth border transitions between Macau and Mainland China, preventing any crossing issues despite its unusual appearance that may intrigue onlookers.
