The Betsiboka Bridge is an impressive engineering feat located on the RN4 national road near Maevatanana. It spans the Betsiboka River, which is internationally famous for its distinct reddish-brown water caused by heavy siltation and soil erosion. The original bridge was constructed in the 1930s in the style of Gustave Eiffel and was once among the longest suspension bridges on the island. During World War II in 1942, the bridge was destroyed by Vichy French forces to hinder the British advance, but it was later rebuilt to restore the vital link. The current steel structure is a critical artery for land transport between Antananarivo and the northwestern port city of Mahajanga. Its design reflects the functionalist aesthetic of the colonial era, built to withstand the extreme hydraulic pressure during the rainy season. For travelers, the bridge features a panoramic vantage point to witness the river's immense scale and the surrounding savannah landscape.
