A morning construction accident on the Mérida-Tetiz federal road quickly turned into an emergency scene after workers on the Tren Maya cargo project damaged a natural gas duct. The incident sent gas into the air, forced road closures, and brought state and federal responders to the area. Officials later said the leak was controlled quickly and no injuries were reported, but the case raises fresh questions about safety checks around major infrastructure work.
Gas duct rupture shuts down Mérida-Tetiz road
Workers on the Tren Maya cargo project damaged a natural gas duct Tuesday morning along the Mérida-Tetiz federal road in Yucatán, causing an emergency response and temporary road closures near the area.
The incident occurred during drilling work for the cargo rail project. Authorities said the damaged line was a 12-inch natural gas duct, and the rupture released a large white plume visible from a distance.
Emergency crews responded to the scene, including state civil protection officials, public security personnel, firefighters, the National Guard, the Army, and gas company workers. Traffic was blocked while crews worked to control the leak and reduce risk to nearby drivers and workers.
Authorities say valves were closed quickly
Yucatán civil protection officials said the gas valves were closed within 10 minutes. No injuries were reported.
Officials also said the white plume seen after the rupture was gas escaping under pressure, not smoke from a fire. Natural gas disperses more quickly in open air than LP gas, but authorities still treated the incident as a high-risk emergency.
The Mérida-Tetiz road was closed as a precaution while crews secured the area. Some reports placed the incident near kilometer 13, close to the route toward Hunucmá.
Human error cited in the incident
State civil protection officials described the rupture as a human error and said the area had warning signs indicating that no drilling should be done there.
The agency urged construction companies to verify duct locations before carrying out excavation or drilling work. That warning applies beyond this incident, especially in fast-growing areas where roads, utilities, industrial sites, and large public works often overlap.
Specialized personnel were expected to repair the damaged duct. Authorities said the response helped prevent injuries and further risk in the area.
Cargo project is part of a larger rail expansion
The Tren Maya cargo system is being developed as part of a broader plan to move freight across the Yucatán Peninsula and connect production zones with ports and logistics hubs.
Government project information describes planned cargo extensions and multimodal terminals tied to Progreso, Poxilá, Cancún, and other points in the southeast. In Yucatán, the cargo expansion includes rail connections intended to link the Mérida area with Progreso and nearby industrial zones.
The accident on the Mérida-Tetiz road does not appear to have affected passenger service. However, it adds public attention to construction safety as the freight portion of the project continues.
For residents and travelers in Yucatán, the main immediate impact was road disruption and concern over the gas release. For the broader project, the incident highlights the need for clear coordination between contractors, utility operators, and emergency agencies before work begins near buried infrastructure.
