Project Description
1 pixel image

Subject to the results of the Environmental Impact Statement in progress, the US 36 Corridor and Longmont Extension includes a 38.1-mile commuter rail line along the existing railroad right-of-way between Denver Union Station in Downtown Denver and Longmont (through Boulder). In addition to commuter rail, 18 miles of BRT/HOV lanes are proposed in the median of US 36 between I-25 and the Table Mesa park-n-Ride in Boulder. FasTracks includes funding for slip ramps and access improvements to park-n-Rides. In addition, FasTracks will provide funding for centerline BRT stations, platforms and a proportional share of HOV lanes ($66 million) as part of future CDOT improvements to US 36.

The US 36 Corridor project will enhance transit connections between Downtown Denver and the communities of Westminster, Broomfield, Louisville, Superior, Boulder, and Longmont. The project improvements will provide more options to commuters and others traveling along heavily congested US 36 which is expected to see a 49 percent increase in traffic by 2025.

Project Benefits
1 pixel image
  • Seven new commuter rail stations
  • Slip ramps and access improvements to bus park-n-Rides along US 36
  • Peak hour travel time savings (transit vs auto) in 2025:
    • Longmont to Downtown Denver: 57 minutes (Commuter Rail) faster by transit
    • Boulder to Downtown Denver: 61 minutes (Bus Rapid Transit) faster by transit
  • Percentage of people using transit in the peak travel period: currently 16%; with FasTracks 18%
  • Economic Development Opportunities:
    • 71st/Lowell - The City of Westminster is examining the potential of redevelopment of over 100 acres surrounding the 71st/Lowell station in the south Westminster area. The City’s plans focus on transit-oriented development and traditional neighborhood development.
    • 30th/Pearl - The City of Boulder has planned the development of the Boulder Transit Village on a 7.5-acre parcel adjacent to the 30th/Pearl station. The transit village will be a medium to high density development with a mix of residential, open space, and commercial uses.
