I-25 Lone Tree Mobility Hub Improvements | Construction Phase

Travel Advisories | I-25 Full Overnight Closures

Full overnight closures on I-25 expected Oct. 26 and 29 for pedestrian bridge installation. Southbound I-25 closure: Monday night, Oct. 26. Northbound I-25 closure: Thursday night, Oct. 29. Trainstation Circle will be closed to through-traffic while crews install the bridge. Additional overnight single- and double-lane closures will occur on I-25 in both directions during the week as crews position equipment. Refer to the Traffic Impacts section for details.

About the Project

As the state continues to grow, the Colorado Department of Transportation (CDOT) and its partners continue to plan and implement high-quality transportation infrastructure and services to accommodate Colorado’s changing needs. Integrating multimodal choices enables the transportation system to move goods and people throughout the network. CDOT’s “Mobility Hub” re-envisions the traditional park-and-ride transit stop. The Mobility Hubs are transportation centers at select locations that emphasize multimodal options, including:

  • Seamless mode-to-mode transitions
  • Real-time passenger information
  • Passenger convenience
  • Opportunities to create transit-friendly development in surrounding areas

The Lone Tree location will be the newest mobility hub to undergo construction, connecting to a network of hubs along I-25 from Fort Collins to Pueblo. This transit improvement project will consist of constructing slip ramps along the I-25 northbound off-ramp and southbound on-ramp just south of Lincoln Avenue for use by Bustang transit services. Additionally, the project team will build a pedestrian bridge over I-25 that connects the two transit stops for pedestrian and bicycle access. Pedestrian ramps and stairs will be provided on the west side of the mobility hub between I-25 and Trainstation Circle.

Other infrastructure upgrades will include:

  • Installation of bus shelters
  • New sidewalks
  • A passenger pick-up and drop-off area

The new mobility hub will provide Bustang users access to the light rail, Lone Tree’s Link on Demand transit service and connect to the future Lone Tree City Center.

  • Allowing connectivity through the Lincoln Avenue interchange to employment and housing locations

Work Schedule

  • General working hours are from 7 a.m. to 5 p.m., Monday through Friday
  • Night work will be limited, but is anticipated intermittently throughout the course of construction
    • General nighttime hours will occur from 7 p.m. to 5 a.m., Sunday night through Friday morning

Traffic Impacts

Southbound I-25 closure: Monday night, Oct. 26

  • Single- and double-lane closures on southbound I-25 at Lincoln Avenue, Exit 193, from 6 p.m. to 11 p.m.
  • A northbound I-25 lane will close between Ridgegate Parkway and Lincoln Avenue at 7 p.m.
  • At 11 p.m., all southbound lanes will close at Lincoln Avenue, as well as the on-ramps from Lincoln Avenue to southbound I-25
  • All lanes and ramps are expected to reopen at 6 a.m.
  • During the full closure, drivers will be detoured off southbound I-25 at Lincoln Avenue, east to South Peoria Street and south to Ridgegate Parkway. Motorists can then get back on southbound I-25 at the Ridgegate Parkway on-ramp

Northbound I-25 closure: Thursday night, Oct. 29

  • Single- and double-lane closures on northbound I-25 from south of Ridgegate Parkway to Lincoln Avenue (MP 189.8 to MP 192.6) between 6 p.m. and 10 p.m.
  • An additional single lane on southbound I-25 will close at Lincoln Avenue from 7 p.m. to 9 a.m., Friday
  • At 10 p.m., all northbound lanes will close between Ridgegate Parkway and Lincoln Avenue
  • All northbound lanes are expected to reopen at 5 a.m., Friday
  • While northbound lanes are closed, drivers will be detoured off northbound I-25 at Ridgegate Parkway, east to South Peoria Street, north to Lincoln Avenue and west on Lincoln Avenue to use the northbound I-25 on-ramp.

  • Permanent lane reconfigurations are currently in place on north and southbound I-25 surrounding Lincoln Avenue. Lanes are restricted to an 11-foot width and speeds have been reduced to 55 MPH on southbound I-25 and 65 MPH on northbound I-25.
  • Permanent barriers are in place on the northbound I-25 off-ramp to Lincoln Avenue, which has been reduced to a single lane. The eastbound Lincoln Avenue to southbound I-25 on-ramp has been reduced to an 11-foot width.
  • Travel through the work zone with caution. Slow down, leave plenty of room between vehicles and watch for crews and equipment.
  • During active working hours, please be aware of trucks entering and exiting the ramps and the median.
  • The project team is working closely with Bustang and other transit services to limit disruption to current transportation schedules at Lincoln Avenue.
  • There will be some pedestrian detours while sidewalks are being constructed in the surrounding area.
