The infrastructure is 95% complete and will be finished in the forthcoming months. The tunnel measures 25 metres in width and 750 metres in length, of which 696 metres are underwater. The starting point is 12 metres underwater, dropping to around 15 metres at the midpoint.

The work project will allow users to cross the city in only three minutes, saving them considerable time. The same journey, on a road used by over 22,000 vehicles, currently takes 45 minutes.

At the event, the authorities emphasised the technical complexity of the work and its progress. The access point to Colón street was also opened at the event, which allows areas of Coatzacoalcos to be reconnected: the Coatzacoalcos pier, Malpica Avenue and General Anaya. The opening of this street will benefit residents of the Esfuerzo de los Hermanos del Trabajo neighbourhood, as well as visitors to the 20th of November Market and the Port Authority.
