What happened
Denver International Airport (DEN) is planning to convert portions of its existing underground baggage tunnels into pedestrian walkways. This infrastructure change aims to provide passengers with an alternative to the airport's Automated Guideway Transit System, which connects the main Jeppesen Terminal to Concourse A and serves as the sole link between Concourses A-B and B-C. The move follows recent mechanical glitches that forced the deployment of shuttle buses. The project is part of DEN's "Vision 100" strategic plan to handle 100 million annual passengers. United, American, and Southwest Airlines have endorsed the addition of these walkways
