DIA opens new east security checkpoint and closes busy south lanes
Denver International Airport's brand new 17-lane east security checkpoint opens Tuesday, replacing the heavily trafficked south checkpoint.
Why it matters: The move marks a major milestone in the airport's $2.1 billion Great Hall renovation project, set to wrap in 2027.
How it works: Travelers will now be routed through either the east or west checkpoints, both on Level 6.
After screening, travelers can take the new triple escalator to catch the train — or reach Concourse A by crossing the A-Bridge, which reopens Tuesday after an eight-month closure during construction.
Zoom in: The new checkpoint — a mirror image of the west security checkpoint, which opened in early 2024 — has three separate entrances categorized by traveler group:
East security 1: For standard passengers
East security 2: For restricted access, including DEN Reserve, military, passengers with disabilities and Clear customers without TSA PreCheck
East security 3: For TSA PreCheck and Clear customers with TSA PreCheck
What they're saying: The new checkpoint "will improve the safety and security of the screening process and provide a more efficient experience for passengers," Douglas Cruz, TSA's federal security director for Colorado, said in a statement.
The fine print: South PreCheck lanes will remain open intermittently based on TSA staffing and passenger demand through Sept. 2 before permanently closing, DIA spokesperson Ashley Forest told Axios Denver.
All equipment will remain in place through that date in case it's needed.
The big picture: DIA is now the third busiest airport in the U.S. and sixth worldwide. Its $2 billion renovation is aimed at scaling up for continued growth.
What's next: Eight more security lanes are slated to open on the north end of Level 5 in late summer 2026.
