Firestone-Longmont Mobility Hub

About the Project

Colorado Department of Transportation is reorganizing and expanding resources to create more multimodal options statewide.  Adding the Firestone-Longmont mobility hub will enable greater use of Bustang, the statewide transit system, to encourage ride sharing instead of single-occupant vehicle use.

Benefits of Project

The hub will improve multimodal access to promote regional transit and include:

  • A northbound pedestrian pick-up and drop-off platform along the I-25 off-ramp
  • A new platform on southbound Frontage Road just before the entrance of the southbound on-ramp
  • A sidewalk and pedestrian underpass to connect users from the Park-n-Ride on the east side of I-25 to the station platforms on the west side of I-25
  • Greater capacity with 269 parking spaces
  • Large sidewalks and bicycle storage racks allow for multiple modes to utilize the hub and enhance multimodal connectivity
  • Bus shelters will be installed with an electronic public information board with real-time Bustang departure and arrival schedules.

Traffic Impacts

East I-25 Frontage Road

  • The closure will be in place until March 15. A posted detour that goes through town has been approved by Firestone.
