About the Projects

Boulder County, CDOT and RTD are closely coordinating the dual transportation projects on the Diagonal Highway to improve mobility for Boulder, Longmont and adjacent communities. User-friendly connections between the commuter bikeway, improved pedestrian crossings, bus queue bypass lanes, BRT stations and Park-n-Rides will provide a variety of new transportation options in the CO 119 corridor that enhance safety, accessibility and equity, while reducing climate change and air quality impacts. 

The projects are the result of the 2014 Northwest Area Mobility Study (NAMS) and the 2019 Multi-Modal Planning and Environmental Linkages Study (PEL).
