The road layout included the following main structures:
The main bridge
The bridge is a cable-stayed structure, 608m long, with a central 350 m span and two lateral spans of 129 m each. The navigable canal has a free horizontal width of 300 m and a free height of 50.30 m.
The bridge deck is a continuous structure consisting of two longitudinal 1.50 x 1.75 m beans and a 30 cm thick concrete slab, reinforced by cross beams every 5.20 m. After construction of the central and anchoring piers, work began on the deck from the central pier, with the assembly of 10.40 m long segments.
Each of the main piers is formed by two rectangular box framed shafts, tapering from a 6 x 2.75 m cross section at the base to 4 x 2.75 m at an elevation of 106.25 m; this cross-section is retained up to the top elevation of 133.25 m.
Each main pier is founded on 26 piles (2 m diameter) driven to a maximum depth of 60 m.
The east viaduct
The east viaduct provides access to the main bridge on the Victoria side, and is 2,368 m long. It consists of 39 spans, each 60 m long, and an initial span of 46 m. The viaduct pile foundations are 2 m diameter piles to a maximum depth of 52 m.
The west viaduct
This viaduct provides access from the Rosario side, and is 1,122 m long. It consists of 32 spans, each 35m long.
Minor bridges in the Islands area
The twelve bridges have a total length of 8,184 m and cross the various minor watercourses in the Paranà valley.
The road runs on 47.15 km of embankments. The transversal cross-section has a crest width of 15 m.
