Denver International Airport announced plans to convert its underground baggage handling tunnels into pedestrian walkways for travelers, with construction scheduled to begin in 2027.

The airport's extensive tunnel system, which currently houses automated baggage conveyor systems, has been the subject of various conspiracy theories since the airport's opening in 1995. The underground infrastructure spans beneath the airport's terminals and concourses.

Airport officials have not yet released detailed plans for how the tunnel conversion will be implemented or what specific areas will be accessible to passengers. The project represents a significant infrastructure modification that would give travelers access to previously restricted underground areas.

Denver International Airport, which serves as a major hub for domestic and international flights, has previously acknowledged the conspiracy theories surrounding its underground facilities while maintaining that the tunnels serve operational purposes for baggage handling and airport logistics.

The timeline for the pedestrian walkway project suggests a multi-year planning and construction process, though airport officials have not provided cost estimates or detailed architectural plans for the conversion.
