Active road construction in Colorado Springs focuses on major corridor expansions along Interstate 25, Powers Boulevard (CO-21), and Marksheffel Road, alongside neighborhood resurfacing funded by the City's 2C sales tax initiative. Commuters can monitor real-time lane closures, signal updates, and municipal paving schedules through the COtrip system and the City of Colorado Springs Public Works Department.
Major Infrastructure Initiatives Across El Paso County
Road construction in Colorado Springs operates under a multi-jurisdictional framework managed by the Colorado Department of Transportation (CDOT Region 2), the City of Colorado Springs Public Works Department, and El Paso County. Funding and execution are primarily driven by voter-approved initiatives, including the Pikes Peak Rural Transportation Authority (PPRTA) capital projects and the municipal 2C local street paving program.
As the Pikes Peak region experiences sustained demographic expansion, regional transportation networks face elevated traffic volumes on critical arterials. Engineering strategies prioritize capacity additions, grade-separated interchange conversions, and pavement rehabilitation to enhance regional mobility and freight efficiency.
- CDOT Region 2 (I-25, US 24, CO-21)
- City of Colorado Springs (Arterials & Local Streets)
- Pikes Peak RTA & 2C Sales Tax
- Arterial Corridor Widening
- Subgrade & SMA Resurfacing
- Pikes Peak RTA & 2C Sales Tax
Funding Mechanisms for Regional Mobility The continuous maintenance and expansion of Colorado Springs roadways rely on distinct revenue channels. The 2C sales tax is a dedicated voter-approved local tax used exclusively for residential and collector street resurfacing. Parallel to 2C, the Pikes Peak Rural Transportation Authority allocates regional sales tax dollars directly to major capital improvements, safety projects, and transit operations across participating municipal jurisdictions.

Interstate 25 Corridor Upgrades
Interstate 25 serves as the primary North-South mobility spine for El Paso County. CDOT Region 2 operational improvements focus on bottleneck relief, bridge replacement, and acceleration/deceleration lane lengthening:
- North Nevada Avenue & Rockrimmon Boulevard Interchanges: Pavement reconstruction, bridge structure rehabilitation, and improved ramp metering setup to stabilize merge speeds.
- South I-25 & Academy Boulevard Interchange: Operational enhancements, concrete slab replacement, and bridge deck overlays targeting heavy military and commercial freight traffic entering Fort Carson.
- I-25 Ramp & Auxiliary Lane Expansions: Lane expansions between Fillmore Street and Garden of the Gods Road designed to smooth weave patterns during peak commuting hours.
Powers Boulevard (CO-21) Corridor Transformation
Powers Boulevard is transitioning from an express arterial with signalized intersections to a grade-separated express corridor. This continuous project reduces intersection delay and lowers rear-end collision rates.
- Grade-Separated Interchanges: Construction of overpasses and underpasses eliminating traffic signals at high-volume junctions such as Airport Road, Stetson Hills Boulevard, and Dublin Boulevard.
- Access Management Implementation: Right-in/right-out conversions and frontage road connections to isolate local business turning maneuvers from high-speed thru-traffic.
Marksheffel Road Widening and Alignment
Serving as the primary eastern beltway for expanding residential developments, Marksheffel Road is undergoing systematic widening from a two-lane rural cross-section to a four-lane divided arterial.
- Segment Scope: Multi-phase widening stretching between US 24 and Space Center Drive, incorporating concrete curb and gutter, storm sewer infrastructure, and dedicated multi-use paths.
- Bridge Replacement: Installation of upgraded drainage culverts and modern bridge decks capable of handling 100-year flood flows along Jimmy Camp Creek tributaries.
2C Street Resurfacing Program
The City of Colorado Springs Public Works Department oversees the 2C local street paving initiative, applying asphalt overlays to neighborhood streets and major municipal collectors:
- Pre-Paving Concrete Repair: Utility adjustments, curb ramp compliance upgrades under the Americans with Disabilities Act (ADA), and damaged curb/gutter removal prior to milling.
- Rotomilling and Asphalt Placement: Cold milling existing deteriorated asphalt layers followed by the placement of high-durability hot-mix asphalt (HMA) or Stone Matrix Asphalt (SMA).

Environmental and Geological Factors Driving Road Repairs
Road construction frequency in Colorado Springs is directly tied to the unique geological and climatic conditions of the Pikes Peak region. Infrastructure planning must account for severe environmental stress factors:
- Pikes Peak Climate / Geology
- Freeze-Thaw Cycles (300+ annual sun/frost shifts): Asphalt Cracking
- Expansive Bentonite Clay (Subgrade swelling): Roadbed Deformation
- High-Elevation UV Exposure (Binder oxidation): Pothole Formation
High-Frequency Freeze-Thaw Cycles
Colorado Springs registers over 300 days of sunshine annually, paired with sharp temperature fluctuations during winter and spring. Surface temperatures on dark asphalt can rise well above freezing during afternoon sunlight, allowing snowmelt to penetrate porous pavement. Rapid nocturnal freezing causes water inside subbase voids to expand by approximately 9%, creating internal hydraulic pressure that fractures the asphalt matrix and causes potholes.
FREEZE-THAW POTHOLE CYCLE:
- Water Enters Cracks (Snowmelt/Rain)
- Ice Expands Subgrade (Night Freezing)
- Pavement Collapses
Expansive Soils and Subgrade Stabilization
The soil geology along the Front Range contains significant concentrations of expansive bentonite clay. When moisture levels shift, these soils expand and contract, exerting upward displacement forces on rigid concrete slabs and flexible asphalt pavements. Engineering solutions applied in local work zones include:
- Chemical Subgrade Stabilization: Hydrated lime or Portland cement injection into subgrade soils to neutralize expansive properties.
- Geogrid Reinforcement: Polymer synthetic grid placement beneath aggregate base courses to distribute axle loads over weak subgrade soils.
Advanced Asphalt Formulation
To withstand extreme UV radiation and severe thermal swings, transportation engineers specify modified asphalt mixtures across major municipal corridors:
- Stone Matrix Asphalt (SMA): A gap-graded aggregate mix bound by polymer-modified asphalt cement, offering high resistance to rutting and fatigue cracking under heavy vehicle loads.
- Warm-Mix Asphalt (WMA) Technologies: Additives allowing lower production and compaction temperatures, reducing thermal stress during placement and lowering greenhouse gas emissions during construction.

- El Paso County Citizen Connect: Digital portal for tracking county-maintained rural road construction, gravel road grading, and bridge replacement schedules.
Work-Zone Navigation Practices
- Execute Late Merging (Zipper Merge): When lane reductions occur, drivers should use both open lanes up to the designated merge point, then alternate turns entering the single open lane. This reduces tailback length by up to 40%.
- Observe Variable Speed Limits: Speed reductions in major work zones—such as I-25 construction corridors—are legally enforced. Fines are doubled in active work zones when workers are present.
- Identify Local Arterial Bypass Routes: Utilize secondary north-south arterials (Nevada Avenue, Union Boulevard, Voyageur Parkway) when Powers Boulevard or I-25 experience major incident delays.
Reporting Road Hazards and Potholes
Residents can report hazardous road conditions, damaged signage, or severe potholes directly to municipal maintenance crews:
- City Limits: Use the GoCOS mobile application or online service portal managed by the City of Colorado Springs Streets Division.
- Unincorporated El Paso County: Submit service requests through the El Paso County Department of Public Works online portal.
- State Highways & Interstates: Submit infrastructure inquiries directly to CDOT Region 2 customer service representatives.

Frequently Asked Questions
What is the 2C paving program in Colorado Springs?
The 2C program is a voter-approved dedicated sales tax initiative in Colorado Springs that funds the repair and resurfacing of city streets.
It provides dedicated municipal funding used exclusively for concrete curb repair, ADA ramp updates, rotomilling, and asphalt overlay placement across residential and collector roadways.
How do I check active lane closures on Interstate 25 in Colorado Springs?
Active lane closures and highway travel delays can be checked in real time using CDOT's official COtrip monitoring platform.
The service provides live stream camera access, electronic message sign displays, mapped lane closure lists, and automated travel alerts for I-25, US 24, and CO-21.
Why is road construction so frequent in Colorado Springs during the summer?
Summer construction peaks due to temperature requirements for asphalt placement and the severe winter freeze-thaw damage that requires spring repair.
Hot-mix asphalt requires warm ambient and surface temperatures to achieve proper compaction density, while freeze-thaw cycles during winter break down older pavement structures, requiring immediate warm-weather rehabilitation.
Who is responsible for fixing potholes on Powers Boulevard?
The Colorado Department of Transportation (CDOT Region 2) is responsible for maintaining Powers Boulevard (CO-21), as it is designated a state highway.
While the road runs through Colorado Springs, state maintenance crews handle asphalt patching, snow removal, and structural paving, rather than the municipal Public Works department.
How does the "Zipper Merge" work in active work zones?
The zipper merge requires drivers to use both travel lanes up to the point of the lane closure, taking alternating turns merging into the open lane.
This method maximizes available road space, balances lane speeds, and reduces total traffic queue lengths before construction bottlenecks compared to early merging.
Where can I report a damaged curb or dangerous road condition within city limits?
Road hazards, damaged curbs, or dangerous potholes within city limits should be reported through the official GoCOS mobile app or the City Streets Division web portal.
Submissions are assigned directly to Public Works maintenance crews for site inspection, priority evaluation, and scheduled repair.
