It has a total length of 1.14 kilometers, of which 696 meters comprise the submerged part. The tunnel was executed using the “Cut and Cover” system. 

The Coatzacoalcos tunnel represents a technological innovation, since under the Immersed-tunnel Method technique it allows prefabricating reinforced concrete sections of the tunnel in a dry dock, preparing them for flotation, towing them and placing them on the bottom of the seabed without it being necessary. use special underground drilling machinery.
