Academy Boulevard Corridor Revitalization
The Academy Boulevard corridor remains one of the city's highest-volume commercial arterials. 2026 operations focus heavily on subgrade stabilization, full-depth pavement reconstruction, and multimodal enhancements between East Bijou Street and Fountain Boulevard. Crews are replacing deteriorating sub-base materials with cement-treated aggregate to withstand heavy transit loads, while upgrading traffic signals to adaptive control technology to reduce corridor latency.
Marksheffel Road Widening and Safety Improvements
Serving as a vital eastern bypass for El Paso County, Marksheffel Road is undergoing multi-phase expansion from two to four lane divided configurations between Space Center Drive and Highway 94. The 2026 phase integrates concrete box culvert installations to manage storm run-off across Sand Creek tributaries, alongside elevated bridge structures at major railway crossings to eliminate vehicular bottlenecks.
Powers Boulevard (State Highway 21) Grade Separations
CDOT Region 2 continues its long-term conversion of State Highway 21 into an expressway standard. Priority structural work in 2026 focuses on grade-separated interchanges at key intersections, reducing signalized stops between Airport Road and Research Parkway. Continuous concrete paving and median barrier construction are underway to increase throughput speed while mitigating broadside collision hazards.
Interstate 25 Operational Enhancements
Along the I-25 spine through central Colorado Springs—stretching from the Fillmore Street interchange down to South Academy Boulevard—work crews are executing auxiliary lane additions, pavement rehabilitation, and ramp metering upgrades. These developments address severe morning and evening commute congestion points adjacent to Fort Carson and downtown access points.
The 2C Street Paving Program: Neighborhood Resurfacing Standards
The voter-approved 2C sales tax initiative remains the primary funding mechanism for neighborhood street resurfacing across Colorado Springs. Operating under strict quality-control protocols, the 2C program addresses secondary and residential roadway degradation caused by aggressive freeze-thaw cycles.
2C Operational Workflow StandardPrior to applying fresh hot-mix asphalt (HMA), field crews inspect sub-surface utilities, replace non-compliant ADA curb ramps, and mill existing surface layers down 2 to 3 inches. Paving only proceeds once subgrade deflection testing meets municipal deflection thresholds, preventing premature fatigue cracking.
The 2C program prioritizes asphalt mixes tailored for high-elevation thermal stresses:
- Stone Matrix Asphalt (SMA): Deployed on high-traffic collector streets to resist rutting and surface shearing under heavy vehicle axle loads.
- Performance Grade Binders (PG 64-28 & PG 76-28): Modified asphalt binders designed to remain flexible during sub-zero winter drops without softening during high-temperature summer peaks.
- Concrete Curb, Gutter, and Ramp Standardization: Pre-paving concrete operations ensure surface water drains efficiently into storm sewers, eliminating standing water that accelerates pavement deterioration.

Technical Pavement Engineering in High-Altitude Environments
Civil construction in Colorado Springs must overcome unique geographic challenges, including highly expansive clay soils (bentonite), extreme diurnal temperature fluctuations, and intense ultraviolet radiation. Engineering teams utilize targeted mitigation strategies during design and execution.
Soil Stabilization & Base Preparation
El Paso County subgrades frequently contain expansive clays that shrink and swell with moisture variations. To prevent frost heaving and severe longitudinal cracking, contractors employ chemical stabilization—injecting quicklime (calcium oxide) or Portland cement into the top 12 to 18 inches of subgrade. This chemically alters the soil structure, lowering its plasticity index and establishing a rigid foundation.
Drainage Engineering & Snow Compression Resistance
Uncontrolled surface runoff poses the greatest single threat to local roadway integrity. Water penetrating micro-fissures freezes during winter nights, expanding by approximately 9% in volume and causing severe potholing. Reconstruction projects mandate open-graded friction courses (OGFC) or permeable edge drains that rapidly channel moisture away from structural pavement layers into the municipal storm infrastructure.

Seasonal Paving Windows and Weather Constraints
Asphalt paving and concrete operations in the Pikes Peak region operate within tight temporal windows defined by CDOT and city technical specifications. Environmental conditions directly dictate structural longevity.
Ambient and Surface Temperature Requirements
Standard Hot Mix Asphalt (HMA) placement mandates strict ambient and ground temperature cutoffs:
- Lower Lift Placement: Ambient air temperature must be at least 40°F (4°C) and rising, with surface temperatures verified above freezing.
- Surface/Wearing Course Placement: Ambient temperature must reach a minimum of 50°F (10°C) with surface temperatures at 60°F (16°C) or higher.
- Compaction Timing: High-altitude ambient conditions accelerate asphalt cooling rates. Compactor rollers must complete initial density passes before the mix temperature drops below 185°F (85°C) to prevent under-compacted, porous pavement.
Cold-Weather Emergency Operations
When urgent roadway repairs must occur outside the April-to-October window, crews utilize warm-mix asphalt (WMA) additives or high-performance cold patch compounds. WMA technologies lower the binder viscosity, permitting proper compaction at temperatures 30°F to 50°F lower than conventional HMA.
Driver Navigation, Commuter Safety, and Traffic Management
Heavy construction active throughout El Paso County presents operational challenges for commuters, freight transport, and emergency services. Mitigating delays requires dynamic travel planning and adherence to work zone protocols.
Real-Time Routing and Traveler Tools
- COTrip Information System: CDOT's primary real-time mapping service provides updated closure reports, live snowplowing tracking, and mountain pass restrictions.
- Colorado Springs Traffic Management Center (TMC): Monitors municipal CCTV cameras and controls adaptive signal timing along major detour routes like Union Boulevard and Nevada Avenue to absorb diverted volume.
- Navigation Apps: Waze, Google Maps, and Apple Maps ingest regional lane-closure feeds, but drivers should remain alert for sudden temporary flagger setups in residential 2C paving zones.
Work Zone Safety Compliance
Work zone traffic control complies strictly with the Manual on Uniform Traffic Control Devices (MUTCD). Fines for speeding in active Colorado work zones are doubled when workers are present. Drivers must maintain safe follow distances, obey temporary automated speed enforcement zones, and change lanes early when approaching merging taper zones.
Frequently Asked Questions
What is the 2C paving program in Colorado Springs, and how does it affect my street?
The 2C program is a voter-approved local sales tax initiative dedicated exclusively to resurfacing residential and arterial streets across Colorado Springs. When your street is scheduled for 2C paving, crews will first repair damaged curbs, gutters, and sidewalk ramps, mill the old asphalt surface, and then lay a fresh asphalt wearing course, typically requiring temporary daytime street parking restrictions.
Why does road construction in Colorado Springs take place primarily between April and October?
Hot mix asphalt requires warm ground and ambient temperatures to achieve proper compaction density and structural bonding. Cold weather causes asphalt mix to cool too quickly during transport and placement, leading to premature cracking, poor compaction, and early failure under freeze-thaw cycles.
How can I report a severe pothole or damaged roadway in Colorado Springs?
Potholes and hazardous road conditions on city-maintained streets can be reported directly to the City of Colorado Springs Public Works Department via the GoCOS mobile app or through the online municipal service portal. For state highways like I-25, Highway 24, or Powers Boulevard (SH 21), reports should be submitted directly to CDOT Region 2.
How are major road projects funded in El Paso County?
Road construction is funded through a combination of local sales taxes (such as the 2C program), the Pikes Peak Rural Transportation Authority (PPRTA) regional tax pool, state highway funds administered by CDOT, and federal transportation grants allocated for interstate and regional mobility infrastructure.
What should I do if my vehicle is damaged by road construction or a pothole?
If damage occurs on a city street, you can file a formal notice of claim with the City of Colorado Springs City Attorney's Office within 182 days of the incident, providing documentation such as photos, repair estimates, and exact location details. For damage occurring on state highways, claims must be submitted to the Colorado Office of State Controller.
Optimizing Mobility Across the Pikes Peak Region
Infrastructure development in Colorado Springs represents a critical investment in regional economic resilience, safety, and transit efficiency. While seasonal construction creates temporary travel friction, following real-time traffic updates, observing work zone speed limits, and utilizing alternate arterial corridors will ensure safe and efficient transit across the Pikes Peak region throughout 2026.
