Puente Ñipas, Road bridge in Ñuble Region, Chile

Puente Ñipas is a 600-metre reinforced-concrete road bridge over the Itata River between Ránquil and Portezuelo, in the Ñuble Region. It has 27 spans of 22.40 metres, except the two end spans of 20 metres, and two double-lane rest bays of 24.88 metres that divide it into three equal parts. The roadway between guard rails is 3.50 metres wide.

The Ñipas station opened in 1911–1912 on the second section of the Rucapequén–Tomé branch line, before the bridge existed; until then goods crossed the Itata by barges and small boats. The bridge was built between 1921 and 1923 by the Compañía General de Construcciones, a German firm based in Frankfurt, to the design of the Inspección de Puentes of the Dirección General de Obras Públicas. It linked the vineyards of the Itata Valley to the branch line and is today the only bridge of that system still in use.

At the bridge's southern end, the Ránquil and Itata Profundo wine competition has been held since 1997, alongside the Ránquil Summer Carnival and the Ñipas-Ránquil Beer Festival. The riverbank serves as a summer beach and camping area, and the bridge is a symbol of local identity for Ránquil and Ñipas.

The bridge is visible from surrounding areas and accessible for observation from nearby roads and walkways. Walking along the river banks offers the best views of the structure from different angles.

Puente Ñipas is the only bridge from the Rucapequén–Tomé branch system still in use. Its deck rests on hollow reinforced-concrete tubes founded on piles driven up to 20 metres into the Itata riverbed, and two 24.88-metre passing bays split the 600-metre span into three equal parts.
