RTD Rail Regional Trail

RTD Rail Regional Trail - Formerly ``Union Pacific Rail Regional Trail``

The RTD Rail Trail (formerly known as the “Union Pacific (UP) Regional Trail”) will run from the eastern boundary of the City of Boulder traversing nine miles to Erie using the RTD-owned rail corridor when possible – see map below. The RTD Rail Trail is one of eight planned trails eligible for funding under the 2007 Countywide Sales Tax Ballot Issue.

The first step in trail development will be the master planning process scheduled to begin in early 2018, which will identify needs, opportunities, and constraints of constructing the regional trail.

A public process will be part of the master planning effort. More information will be posted here as it becomes available. If you’d like to be added to the email notification list for this project, send an email to Boulder County Transportation.
