Denver International Airport plans to convert underground baggage tunnels into pedestrian walkways to connect all three concourses [1, 3].
This infrastructure project aims to reduce passenger reliance on the airport's automated train system and improve the overall flow of travelers between terminals. By providing a direct walking alternative, the airport seeks to alleviate congestion during peak travel periods.
The project involves repurposing existing subterranean space specifically used for baggage transport. These new paths will serve as a supplement to the current transit options, allowing passengers to move between the three concourses [1, 3] without relying solely on the train.
According to airport plans, construction is scheduled to begin in 2027 [1]. The project is expected to be completed by 2029 [2].
Officials said the walkways are designed to provide a more flexible transit experience for travelers. The integration of these paths into the existing layout is intended to streamline the movement of people across the massive facility in Colorado.
While the train system remains a primary method of transport, the addition of pedestrian access points is expected to offer a secondary layer of efficiency. The conversion of the baggage tunnels allows the airport to utilize existing footprints rather than building entirely new surface-level structures.

The conversion of baggage tunnels into pedestrian corridors represents a strategic shift toward multi-modal transit within the airport. By diversifying how passengers move between concourses, DIA reduces the risk of total terminal bottlenecks should the primary train system experience mechanical failure or extreme overcrowding.
