Puente Libertad, Road bridge in El Colorado, Argentina

Puente Libertad is a road bridge over the Río Bermejo linking Chaco and Formosa provinces. It carries the extension of Chaco's Ruta Provincial 90 and Formosa's RP 3, about 5 km from El Colorado and 20 km from General José de San Martín. It is one of three crossings forming a communication trident between the two provinces.

Built during the 1950s, the Puente Libertad was formally opened on 8 February 1957 as a road bridge over the Río Bermejo linking Chaco and Formosa. It extends Chaco's Ruta Provincial 90 and Formosa's RP 3, about 5 km from El Colorado and 20 km from General José de San Martín. On 12 February 2007 an interprovincial commission held a ceremony for its fiftieth anniversary and honoured two surviving workers from the construction crew.

The bridge carries Provincial Route 90 in Chaco and Provincial Route 3 in Formosa, forming part of a three-bridge link between the two provinces. On 12 February 2007 a joint Chaco-Formosa commission led by Aldo Leiva, mayor of General José de San Martín, and Formosa deputy Alberto Sánchez of El Colorado held a ceremony marking fifty years since the bridge opened, honouring two surviving workers from the construction crew.

The bridge carries traffic on the route linking Chaco's Ruta Provincial 90 with Formosa's Ruta Provincial 3, about 5 km from El Colorado and 20 km from General José de San Martín. It is one of three crossings between the two provinces, so check conditions on the General Lavalle and General San Martín bridges before setting out.

The bridge carries Chaco Provincial Route 90 and Formosa Provincial Route 3, forming one of three crossings between the two provinces alongside the General Lavalle and General San Martín bridges. Since the Lavalle bridge's structure was endangered by failures linked to the Bermejo current, traffic on Puente Libertad has risen, making it the second most used of the three.
