In 1976 a bridge was inaugurated, spanning the river at km 101 and linking Uruguay with Argentina. The bridge is 5366 m long and the center span is 220 m with a reported clearance of 40 m above the river. To arrive at Fray Bentos from the River Plate, ships normally proceed via the Martín García Channel. From km 0 of the Uruguay river there are four passes, Paso Márquez Punta Caballo, Punta Amarilla and Paso Barrizal, with of about 5.40 m at datum. Both passes are of silt. A safe draught for navigational purposes is dependant on prevailing river water level and is usually around 6.40 m. Pilots and Agents should be consulted beforehand in this respect. At present, the Uruguay River Channel is being deepened at 25' depth until the entrance to the port of Fray Bentos.
