Overview
- The plan, announced Tuesday, May 26, directs Denver International Airport to repurpose portions of its underground baggage tunnels to create walkways linking Concourse A to B and Concourse B to C.
- The airport says designs are being finalized and construction is expected to begin in 2027 after the Jeppesen Terminal Great Hall renovation is complete.
- Officials presented the project as a redundancy to the automated people-mover after repeated train incidents, including a March power outage that prompted a ground stop and passenger delays.
- DEN is simultaneously investing in the train system, replacing original cars as part of a roughly $78.85 million modernization program while pursuing its Vision 100 expansion that added 39 gates and aims to serve up to 100 million annual passengers.
- The tunnels will require engineering, safety and accessibility upgrades before opening and are intended to give travelers a reliable walking option during future train outages; an independent blog has claimed 131 train breakdowns in the past year but that figure has limited sourcing.
