Route 10, ‘East 12th Avenue’, runs from to Denver Union Station to Colfax & Billings.
The route used to start at Federal – Decatur Station was cut back to Union Station at the start of the pandemic. Because of this, the route calls at Union Station twice as it uses Wewatta Street to access its original route on 15th Street.
Every other trip was extended to Colfax & Billings in May 2023.

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 proposed to extend service to Aurora Plaza (Del Mar Cir), however this was implemented even further to Colfax & Billings to provide an operator’s bathroom at the end of the line.
