The third set of locks “has entered its countdown phase,” the Grupo Unidos Por el Canal consortium, responsible for the expansion project, said in a statement.
The 80-kilometer (50-mile) canal, completed in 1914 to offer a short cut and safer journey for maritime traffic between the Pacific and Atlantic oceans, is undergoing a refit to triple its capacity.
Almost all of the work has been completed, and structural and systems tests “are bringing optimal results.”
According to the GUPC, the 16 massive sliding gates of the new locks “are responding positively to all electromechanical tests.”
The GUPC said the fissures would be repaired by strengthening the lock walls with steel.
At least three more months of testing will be carried out before navigation tests begin, the statement said.
The consortium overran its initial $5.25-billion budget, leading to financial disputes with the Panama Canal Authority, the Panama government agency charged with operating the canal.
