COPALA TUNNELS I, II AND III,

This project is part of the most important highway infrastructure work, with the highest density of tunnels and bridges per kilometer that has ever been built in Mexico: the modernization of the Durango-Mazatlán Freeway. Of the 6.21 mi of the project (Section II), 2.7 mi are tunnels and 1.55 mi are bridges. CGAL participated in the construction of the Copala I, II and III tunnels at kilometers 190+579, 192+106 and 195+509 on the new Durango-Mazatlán Freeway. The tunnels have a length of 721 ft, 311 ft and 459 ft, respectively, and a crown width of 39 ft, while the roadway is 22.97 ft wide. The work included an open sky excavation to erect the portals at the entry points, the finishing of the portals, digging of the tunnel and final sheathing. To these works were added those of earthwork, drainage, paving, complementary works, fiber optic installations and signalization.

The tunnels will allow the completion of the new highway, which will benefit the Concordia and Mazatlán municipalities.
