I-25 Ramp Metering Installation

In July,  Colorado Department of Transportation crews began installing a new ramp metering system on 16 on-ramps in both directions of I-25, between mile points 180.5 and 192.9 from Plum Creek Parkway to Lincoln Avenue.  The ramp metering system allows traffic to enter a highway at a rate dependent upon traffic conditions, as a result easing congestion, improving traffic flow and increasing safety.  Crews will be working from 8 a.m. – 5 p.m., Monday – Friday.  Night and weekend work is not anticipated at this time.  However, this project is weather dependent, and the schedule may change.

  • Monday August 19 – Plum Creek Parkway on-ramp to I-25
  • Tuesday – Friday, August 20-23 – southbound Wolfensberger Rd. on-ramp to I-25

Work on this project will also require CDOT to widen three existing northbound ramps: Meadows Parkway, Wolfensberger, and Plum Creek Parkway.

Drivers can expect minor traffic impacts in July, including shoulder closures during operations and traffic slowdowns as trucks are entering/exiting the highway.  In early August, crews will be at multiple sites and work will require temporary single lane or shoulder closures on the ramps.

Monument Hill Road ClosureInformation courtesy of El Paso County 

El Paso County Department of Public Works continues safety and drainage improvements along the southern portion of Monument Hill Road. Work includes construction of a free right turn lane from Monument Hill Road onto Woodmoor Drive, improvements to drainage along Crystal Creek and Monument Hill Road, and road reconstruction.  Due to continued rain events and unexpected site conditions, the road remains closed from the intersection of Woodmoor Drive to the south entrance of the Monument Hill Church.

Phase II work will begin in early July, prior to full completion of Phase I.  Monument Hill Road will be closed from Woodmoor Drive to the south entrance of Palmer Ridge High School, eliminating access from Monument Hill Road to Deer Creek Road.  The Project will provide alternate access for Monument Hill Church. A new detour map is provided with Woodmoor Drive, Furrow Drive and County Line Road serving as the primary detour.  Construction is expected to be substantially complete in August.  Project schedule remains dependent on weather and resources. El Paso County Department of Public Works continues safety and drainage improvements along the southern portion of Monument Hill Road. Work includes construction of a free right turn lane from Monument Hill Road onto Woodmoor Drive, improvements to drainage along Crystal Creek and Monument Hill Road, and road reconstruction.  Due to continued rain events and unexpected site conditions, the road remains closed from the intersection of Woodmoor Drive to the south entrance of the Monument Hill Church.

Drivers who need to use the detour route should plan for added travel time.  Please reduce speeds and watch for workers, equipment, signs and barricades. El Paso County wishes to thank drivers in advance for their cooperation. Full road closure will accelerate the safe and efficient completion of this project.  Funding for this project is provided through PPRTA.

North Surrey Drive Full Closure

Douglas County, in conjunction with the City of Lone Tree, will close North Surrey Drive from Havana Street to Stirrup Lane beginning June 17, 2019, through September 1, 2019. This closure will allow installation of a below-grade trail underpass and utility work that is part of the East/West Regional Trail extension and is necessary to ensure safety of the construction teams and the general public. We recognize the inconvenience this closure causes for those who regularly travel North Surrey Drive and appreciate your patience and understanding. Crews will do everything possible to limit the duration of the closure.

There have been some concerns from citizens regarding Emergency Access in case of fire.  Please view the map showing the emergency access points that are the same as when the road is open. Douglas County has put in an emergency access road around the construction to be open in case of emergency only.


Regional Transportation District (RTD) Southeast Rail Extension (SERE) Project (Light Rail Extension)

As part of RTD’s 2004 voter-approved FasTracks plan to extend rapid transit across the Denver metro region, construction continues for the Southeast Rail Extension Project.

Ridgegate Parkway Widening

The City of Lone Tree will widen RidgeGate Pkwy to provide 2 additional thru-lanes in each direction (between I-25 and Meridian Village Pkwy), building new bridges over Badger Gulch and Happy Canyon Creek, installing 8-feet wide sidewalks (pedestrian) and a 12-feet wide cycle track (bicycles) along this corridor. A portion of the Project will utilize a split alignment.

This Project is split into two phases. Phase 1 includes the two bridges and some earthwork and began in April 2019 with a substantial completion date of September 2019. Phase 2 includes the remaining roadway expansion and is expected to be substantially completed by June 30, 2020.

This is a City of Lone Tree Project – please visit Road Projects in the City of Lone Tree


South I-25 Gap Construction Impacts – Summer 2019

Watch for changing traffic patterns. Throughout the work zone, speed limits will be a maximum 65 mph.  Pay attention!
Two lanes of travel in each direction of I-25 will remain open during daytime peak travel hours. 

Enhanced CDOT safety measures in the I-25 Gap include innovative technology – Variable signs helping to manage traffic in 18 mile-long I-25 South Gap construction project

Earlier this month, the Colorado Department of Transportation integrated a new safety technology into its portfolio, with the installation of Portable Variable Speed Limit (PVSL) signs throughout the I-25 South Gap construction project between Monument and Castle Rock. Eleven signs each are set up in both the northbound and southbound directions and are placed near each entrance ramp to alert all traffic entering the work zone. These allow traffic operators to adjust the speed limits in real-time based on weather conditions, crashes, or construction-related impacts. With this technology, crews can slow down traffic ahead of a crash, incident or weather impact, possibly reducing the likelihood of secondary crashes. In combination with deploying this technology, CDOT has lowered the speed limit in the Gap construction area, worked with the Colorado State Patrol to significantly expand traffic enforcement, along with a broad range of other improvements — identified in partnership with CSP and local partners.

The deployment of PVSLs in the I-25 South Gap project represents the first time this technology has been used in Colorado. They replace existing speed limit signs and display a reduced speed of a maximum 60 mph.

When driving the crossover, motorists should slow down and exercise caution

Upcoming construction impacts summer 2019 for I-25 South Gap Project
Click on the image to view a map of upcoming construction impacts for Summer 2019.
  1. Various crossover configurations to last through 2020 – Greenland Interchange Crossover
    Crews will completely rebuild this one-lane box culvert into a two-lane interchange and construct a new wildlife crossing just to the north of the interchange. As crews build this new bridge in halves, all I-25 traffic will be shifted to one side or the other. Periodic ramp closures will be necessary to reach this configuration.  The middle section of the project along I-25 between Greenland Road and Larkspur will ramp up starting in late July. Heavier construction in this area will require overnight lane closures and extended ramp closures for safety critical work. Detours will maintain local access into Larkspur. More information to come as we approach late-July.
  2. New alignment will last throughout 2019 – Traffic Shift Between Castle Rock and Larkspur
    So far, crews have been working in the median of I-25. This summer, work will shift to the outside.   Two travel lanes will remain open in both directions during peak travel times.  Watch for traffic shifts and overnight lane closures. Lanes will continue to be tight, and shoulder space will vary.
  3. Flagging is underway (full closures slated to start in June 2019) – Frontage Road Work Near Castle Rock – Drainage improvements
    Daily one-way flagging on both frontage roads; overnight flagging on both frontage roads; long-term closures of sections of both frontage roads. However, both frontage roads will not be closed at the same time.
