Construction begins on the Firestone-Longmont mobility hub at I-25 and CO 119

This is one of several mobility hubs along the I-25 corridor that are currently under construction and will significantly improve bus service along I-25

Colorado Department of Transportation

Starting Jan. 30, the Colorado Department of Transportation will begin construction on the Firestone-Longmont Mobility Hub project located at the I-25 and CO 119 interchange.

Communities along the I-25 corridor are continuing to rapidly expand, creating more congested roadways. This is one of several mobility hubs along the I-25 corridor that are currently under construction and will significantly improve bus service along I-25.

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

  • A northbound pedestrian pick-up and drop-off platform along the I-25 off-ramp 
  • A new pedestrian pick-up and drop-off platform on the east side 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

The Firestone-Longmont Mobility Hub is a part of the multimodal connectivity of the I-25 North improvements. For more information visit the project website listed below. The anticipated completion date of the project is August 2024.
