Peak-only 145X trips line up with airport shift changes
RTD Bus Route 145X is an express bus linking Montbello and Green Valley Ranch to Denver International Airport’s Jeppesen Terminal, aimed squarely at airport and logistics workers. It runs on weekdays only and only during peak hours, with trips timed around common shift starts and ends rather than flight banks.
This is a limited-stop commuter route, so it skips many local stops that Route 45 covers and runs faster in the peak direction. Schedules on RTD show service clustered around early morning and late afternoon, with some midday coverage depending on the sheet, but nothing like the all-day pattern of the A Line train.
How to ride from Montbello/Green Valley Ranch to DEN
- 1. Check the current 145X timetable on RTD’s site and confirm there is a trip that matches your shift start or flight time; outside peak windows it simply does not run.
- 2. Go to a signed 145X stop along the corridor in Montbello or Green Valley Ranch; stops are listed by street name and block on the official schedule PDF.
- 3. Have fare ready: standard RTD Local/Regional/Airport fare rules apply, and 145X counts as an airport route, so check if your employee EcoPass or mobile ticket covers the Airport fare zone.
- 4. Board using the front door, tap or show your pass, and confirm with the driver that the bus is heading to Denver International Airport and not short-turning.
- 5. Stay on until the Jeppesen Terminal stop; 145X drops you at the main terminal area, from which you can walk inside and then take the underground train to your concourse.
Who actually uses 145X, and when to skip it
Transit regulars in Denver say they ride 145X when their shifts align with the peak-direction runs, then fall back to the A Line train or other routes for late-night or irregular hours. The route never touches downtown Denver, so tourists staying near Union Station or LoDo usually ignore it and head straight for the rail platform instead.
Complaints on local forums focus on confusion: peak-only airport routes like 145X can disappear from the board for large chunks of the day, leading new riders to wait 30–60 minutes for a bus that is not scheduled at all. The simple fix: treat 145X as a bonus option. If you do not see a trip within your window on the official weekday schedule, move immediately to the A Line or another all-day route instead of waiting.
