Construction of a tunnel for livestock to run through, underneath the train, in Section 3 (Calkini-Izamal Section) of the Maya Train project near Sudzal, Yucatan state, Mexico on December 19, 2022. The Maya Train project is one of Mexican President Andrés Manuel López Obrador’s flagship development projects. Its 1,525-km route will run through five states (Tabasco, Chiapas, Campeche, Yucatán and Quintana Roo states), linking Maya temples like Palenque, Chichen Itzá and Calakmul, the colonial city of Mérida, beach resorts of Cancún, Playa del Carmen and Tulum and protected Sian Ka’an and Calakmul nature reserves. The construction began in June 2020 and has been awarded to private construction companies and the Mexican army. It is scheduled to begin partial operations in December 2023 and finish construction by 2024. Photograph by Bénédicte Desrus
