The Spanish building company, Sacyr, leading the expansion project on the Panama Canal has denied that work at the waterway has been halted despite word to the contrary by the Panama Canal Authority (ACP) reports BBC News. The Panama Canal Authority and the building companies involved are engaged in a dispute over who should foot $1.6bn (£1bn) in extra costs. Citing remarks by president of Sacyr, Manuel Manrique, BBC News report that no date had been set for construction work to stop.
