Panamanian construction firm Constructora Urbana (Cusa) is carrying out improvement works on the David-Boquete highway in western Chiriquí province in four phases, a public works ministry (MOP) communications official told BNamericas.
Completed sections will not be reopened until all work is completed, as bridges along the route have a different schedule from the highway sections, the official added.
Construction, which will cost some US$120mn, is scheduled to take three years to complete, after which Cusa will operate the highway for another three years.
Work involves expanding the 37km highway from two to four lanes on the highway connecting cities David, Dolega and tourist district Boquete. Cusa was awarded the contract in October and work is currently 12% complete, according to a MOP release.
