Current Issues

This route suffers from poor scheduling at ? Station, here buses are timed to depart 3 minutes before W Line trains arrive.

Future Plans

The System Optimization Plan proposes to switch the route’s Downtown Denver destination to Union Station. This is in anticipation of routes 15 and 15L being replaced by Colfax Lynx BRT service from January 2027.
