Armando Emilio Guebuza Bridge, Road bridge over the Zambezi at Caia, Mozambique

The Armando Emilio Guebuza Bridge is a four-lane road bridge on the EN1 highway between Caia and Chimuara, crossing the Zambezi near Caia. It is 2,376 m long and 16 m wide, made of a 1,666 m approach viaduct and a 710 m main span over the river, both prestressed concrete box girders. The main span rests on hexagonal hollow piers founded on four bored piles each.

Construction began in March 2006 and the bridge was officially opened on 1 August 2009, named after Armando Guebuza, then President of Mozambique. It was built by the Portuguese firms Mota-Engil and Soares da Costa from designs by WSP, GRID and Louis Berger Group, at a cost of 65.9 million euros.

The bridge carries the name of a former Mozambican president and marks an important moment in the country's effort to improve infrastructure connections. It links two provinces that were once separated by the river and ferry travel.

The bridge carries the EN1 national road over the Zambezi between Caia and Chimuara, so it is the last crossing of the river before the Indian Ocean. It is 16 m wide with four lanes; the deck runs on a 1,666 m approach viaduct and a 710 m main span.

The main river span is a prestressed concrete box girder built by cantilever construction, with pier spacings of 80 + 4×137.5 + 80 m and a depth tapering from 7.5 m at the piers to 3.5 m at mid-span. The southern approach viaduct, 1,666 m long, was cast on a movable falsework system. The piers are hexagonal hollow sections founded on four bored piles each.
