Don Ca Arch Bridge is not just an architectural structure, but also a historical witness of Vietnam's century-old railway line. According to records, the bridge was built by the French between 1902 and 1906, serving as an important part of the Hai Van Pass railway line—a vital artery connecting Hanoi and Saigon (now Ho Chi Minh City). This entire railway section spans approximately 28 km, passing through 18 bridges and 6 tunnels, with construction beginning in 1899 and completed in 1936.

Designed by French engineers, Don Ca Arch Bridge was built to conquer the treacherous terrain of Hai Van Pass, connecting the two regions of the country across rolling mountains and forests. Over a century has passed, and the bridge has witnessed numerous historical events from the French colonial era through two resistance wars up to the reunification of the nation. Though wearing a coat of moss and traces of time, the bridge still stands proudly amid nature, serving both transportation and becoming a nostalgic tourism symbol of Da Nang.
Notably, The Guardian (UK) once voted the railway route through Hai Van, where Don Ca Arch Bridge is located, as one of the "10 most beautiful coastal railway routes in the world". Today, the image of the arched bridge curving through the ancient forest under a deep blue sky has become a legendary backdrop for photographers and backpackers.
