About
The Nine Arch Bridge (Sinhala: ආරුක්කු නමයේ පාලම; Tamil: ஒன்பது வளைவுகள் பாலம்) also called the Bridge in the Sky, is a viaduct bridge in Sri Lanka and one of the best examples of colonial-era railway construction in the country.
The bridge was designed to accommodate a challenging nine-degree curve and steep gradient. Built entirely by local labor under British supervision, the construction faced significant logistical challenges, including difficult terrain and material transport. Completed in 1919, the bridge used concrete cornice blocks for arch support and locally produced sand-cement blocks for facing.
