The Puente General Manuel Belgrano is a road bridge over the Río Paraná that connects the Argentine cities of Resistencia in the province of Chaco and Corrientes in the province of the same name . It is therefore usually referred to simply as the Puente Chaco – Corrientes . It is named after Manuel Belgrano (1770-1820), an Argentine lawyer, politician and general.
location
The General Belgrano Bridge is 30 km from the confluence of the Paraguay River on the border with Paraguay and is the first bridge below the roughly 250 km away Yacyretá - dam . Down the river, the Túnel Hernandarias, 600 km away between Santa Fe and Paraná, is the first fixed river crossing. This tunnel, opened in 1969, is the oldest fixed crossing of the Río Paraná in Argentina. Another 130 km downstream is the Rosario-Victoria Bridge, completed in 2003 .
description
The Puente General Manuel Belgrano was built from December 1968 to May 1973 according to plans by Ammann & Whitney by a group of Italian and an Argentine companies. It has two lanes and a sidewalk on both sides.
Its main structure is a cable-stayed bridge with spans of 245 m in the main opening and 163.5 m in the side openings as well as the clearance height of 35 m above the flood required by shipping . The A-shaped structure of its two 84-meter high pylons of reinforced concrete is evident from Riccardo Morandi affected, who used it several times to achieve the necessary rigidity of the pylons against the moving over the bridge traffic loads.
The carriageway girders of the cable-stayed bridge as well as those of the adjoining T-beam bridges are made of prestressed concrete . On the western side there are 10 and on the eastern side 4 bridge fields with spans of 80 m, the roadway of which slopes slightly towards the banks.
To protect the pylons from the impact of ships in the river, triangular floating bodies up to 60 m long and 35 m wide are installed as ship deflectors at a distance of several meters upstream and downstream .
This actual bridge over the river is 1700 m long. Together with the ramp bridges on both sides of the land, this results in a total length of 2240 m. Mostly a length of 2800 m is given, which includes some, but not all, of the direct accesses over dams. In the west, the road leads on a dam through the alluvial land and over old river arms, which are crossed by two low, 475 m and 110 m long bridges. The toll booth is located on the edge of this area , around 2.5 km from the bridge. To the east, the ramp bridge leads to the city of Corrientes, which extends to the shore, where traffic is threaded through several lanes into the local streets.
The stay cables were replaced between 1996 and 1997, and renovation work began on the roadway girders and pillars in 2015.
Since the bridge has long been congested due to the increasing traffic, the two provinces agreed in 2014 to build a new bridge, which will be put out to tender at the end of 2015.
