Mexican President Felipe Calderón inspected works on Sinaloa state's Baluarte bridge during a tour to the northwestern state this week, the presidential website reported.
The 1.24km structure will connect Durango and Sinaloa states, and is slated to be the highest suspension bridge in Latin America, with an altitude of 520m at the deepest point of the valley it crosses.
The bridge is part of the 18bn-peso (US$1.44bn) Durango-Mazatlán highway project, connecting the country's northern areas from Mazatlán to Matamoros over the Sierra Madre Occidental mountain range.
"With the Baluarte bridge and Mazatlán-Durango highway, we are really overcoming the challenge and adversity that was involved in crossing these hills," Calderón said during the inspection.
A consortium formed by Tradeco Infraestructura, Aceros Corey, VSL Corporation Mexico and Idinsa is carrying out construction.
