The Coatzacoalcos Underwater Tunnel opened with a formal dedication on April 27 , 2017 , at a cost of 5.398 billion pesos — a 256 % increase over the original budget . Speaking at the dedication , Governor Miguel Ángel Yunes Linares suggested that the tunnel be known as the Túnel Puerto México , in honor of one of the former names of Coatzacoalcos . A piece of concrete fell from the ceiling of the eastbound ( Coatzacoalcos-Allende ) tunnel during the 2017 Chiapas earthquake
