Puente ferroviario Biobío en Coihue, Railway bridge across Biobío River between Los Ángeles and Negrete, Chile.
The Biobío Railway Bridge extends 500 meters across the river with ten 50-meter sections supported by pairs of iron tubular pillars filled with concrete.
Lever, Murphy & Co. constructed the bridge in Viña del Mar during 1890, following designs by engineer Enrique Budge Prats of the State Railway Company.
The bridge represents a crucial connection in Chile's Southern Railway Network, linking the stations of Santa Fe and Coihue for regional transportation.
The bridge's rail height varies between 10 and 14 meters depending on the Biobío River's water level, ensuring continuous railway operations throughout the year.
The structure underwent modifications in 1931 with the addition of parabolic chain reinforcements, and in 1947 the original lattice was replaced with a Warren-type design.
