Overview

• The Túnel Subfluvial Raúl Uranga is identified as the region’s sole subfluvial road tunnel, linking Paraná and Santa Fe beneath the Paraná River.
• Coverage reiterates a 2,397-meter subfluvial segment, with total length reaching 3,479 meters when access ramps are included.
• The structure opened in 1969 and remains central to regional mobility, logistics, and economic integration.
• Reports describe immersed‑tube construction using precast concrete sections fabricated in a dry dock and assembled on the riverbed.
• Sources differ on exact tube count—37 versus 36 plus a smaller section—and one outlet cites about 10,000 vehicles per day without broader verification.
