Work zone safety is a critical concern for contractors operating in Colorado and Wyoming, especially as 2026 brings new regulations, increased construction activity, and heightened risks for both workers and the traveling public. This page provides a comprehensive overview of work zone safety best practices, regulatory updates, and actionable strategies tailored for contractors in the Rocky Mountain region. Whether you are a general contractor, subcontractor, or safety manager, understanding and implementing effective work zone safety measures is essential for protecting lives, complying with evolving standards, and maintaining project success in 2026.
The numbers leave no room for complacency. CDOT reported 31 work zone fatalities in Colorado in 2024—a 75% surge from 2023 and more than the previous two years combined. Denver metro growth, I-25 reconstruction, and Front Range corridor work have placed crews within feet of vehicles traveling 55–65 mph, and the consequences have been fatal.
Nationally, 899 people died in U.S. work zone crashes in 2023, continuing a 50% increase in fatalities from 2013 to 2023. Road users face a serious risk: roughly four out of five work zone deaths involve drivers and passengers rather than workers. The 2025 AGC Work Zone Awareness Survey found 60% of highway contractors reported vehicles crashing into their zones, and 43% reported worker injuries.
Behind these statistics are real lives. In September 2024, CDOT workers Trenton Umberger and Nathan Jones lost their lives in a Colorado work zone intrusion. Their memory underscores why National Work Zone Awareness Week 2026 (April 20–24) must be more than a campaign—it must be a reset for every ABC Rocky Mountain contractor.
These statistics highlight the unique challenges faced by contractors in Colorado and Wyoming, which are explored in the next section.
Denver metro expansion, infill projects, and ongoing I-25 and I-70 reconstruction create dense, complex work zones through 2026. High-volume corridors from Fort Collins through Colorado Springs to Pueblo frequently place workers adjacent to live traffic during lane shifts and shoulder work.
Wyoming highways present parallel challenges. I-25 between Cheyenne and Casper, I-80 across southern Wyoming, and US-85 energy corridor routes see heavy commercial motor vehicles alongside seasonal construction. Variable weather—foothill fog, high plains wind, sudden stops from ice—compresses work windows.
Commercial and industrial projects generate temporary zones along frontage roads, at distribution centers, and at utility tie-ins. Contractors must design these environments to be forgiving by default, assuming some drivers will be speeding, driving while distracted, or failing to obey reduced speed limits and signs.
Understanding these regional realities is essential for managing the human and operational risks present in every work zone, as discussed in the next section.
Speed was a factor in 34% of fatal work zone crashes in 2022, making speed management a central design priority. Typical crash patterns include:
Because four in five fatalities are motorists, contractors must expect vehicles to violate cones, barrels, and posted limits.
Merit shop contractors—companies that operate on a performance-based, open-shop philosophy rather than union agreements—who lead on zone safety can win competitive advantage on prequalification and CM/GC selections.
With these risks in mind, it’s crucial to understand the latest regulatory changes affecting work zone safety, as detailed in the following section.
The December 2024 FHWA update—the first major revision in roughly 20 years—fundamentally changes expectations. The rule now requires positive protection devices (physical barriers such as concrete barriers or movable barriers designed to prevent vehicles from entering work zones and protect workers from traffic) when:
For typical I-25, I-70, I-80, and high-speed arterial projects, barriers are no longer optional. Contractors must coordinate early with owners on traffic control plans to ensure that pay items, staging, and 4–6-week delivery lead times are complete.
Project teams should map their 2026 bids against these triggers and document compliance decisions. The Connecticut work zone safety standards and FHWA guidance provide reference points, though Colorado and Wyoming implementations may vary. ABC Rocky Mountain will brief members on rule details in safety committee meetings.
Understanding these new requirements is key to implementing effective controls on site, which is the focus of the next section.
The 2026 National Work Zone Awareness Week theme, “Safe Actions Save Lives,” applies to both motorists and contractor choices. Field leaders must direct attention to the following core controls:
By implementing these controls, contractors can turn awareness into action. The next section explains how to leverage National Work Zone Awareness Week 2026 as a catalyst for safety improvements.
National Work Zone Awareness Week 2026 (April 20–24), hosted by Connecticut DOT, offers structured touchpoints:
| Day | Focus | Contractor Actions |
|---|---|---|
| Monday | Training Day | – Conduct toolbox talks on near-misses<br>- Enroll supervisors in ABC Rocky Mountain OSHA courses |
| Tuesday | National Kickoff | – Attend virtual events<br>- Share commitments with CDOT/WYDOT sponsors |
| Wednesday | Go Orange Day | – Organize firmwide visibility events<br>- Take crew photos<br>- Conduct inspection blitzes |
| Thursday | Social Media Storm | – Post local stats (31 CO fatalities)<br>- Tag partners<br>- Use official hashtags |
| Friday | Moment of Silence | – Pause to honor Umberger, Jones, and all who face life-threatening exposure |
Use these campaigns to reduce distractions, reset policies, and reinforce safe-driving messages for everyone traveling through your zones.
To maximize the impact of these initiatives, contractors should also take advantage of the resources and support offered by ABC Rocky Mountain, as described in the next section.
ABC Rocky Mountain Chapter provides the resources contractors need to protect crews and the public alike:
Connect with our safety team to review your 2026 plans. The interest in obtaining stronger performance starts with action: register for training, enroll in STEP, and support your crews with the skills they need.
Every barrier installed, every briefing conducted, every policy strengthened is a prerequisite for the outcome we all want: sending workers and every driver passing through a member’s work zone home safely. That’s merit shop excellence in action.
For more detailed guidance, see the frequently asked questions below.
The rule applies to any project using federal-aid highway funds, including smaller interchange, frontage road, and bridge jobs. If your zone meets trigger conditions (45+ mph, high volumes, or two-week duration), positive protection expectations apply regardless of project size. Even on privately funded work, adopting the standard can reduce liability.
Document your risk assessment, reference FHWA guidance, and present cost-benefit data tied to crash reduction and schedule protection. Address this during preconstruction or value engineering. ABC Rocky Mountain can provide talking points and industry data to support these conversations with public and private owners.
Prime contractors remain responsible for enforcing rules for everyone entering the zone. Require brief orientations covering access routes, speed expectations, PPE, and emergency procedures. Add contractual language making compliance mandatory. Extra caution is warranted for independent haulers who may be unfamiliar with your detours and route configurations.
Queue-warning systems, connected arrow boards, smart sensors, and telematics with geofence alerts can materially improve behavior. Even simple tools—speed feedback trailers and digital checklists—help. Consider piloting technology on one high-risk 2026 project (such as a congested I-25 segment) before scaling. Fines doubled in many states for work zone violations provide additional enforcement support.
Schedule an initial safety program review with our team and enroll in STEP during your first year to benchmark current practices. Join safety committees, attend quarterly roundtables, and designate an internal liaison to receive training calendars and FHWA/CDOT/WYDOT updates. The course catalog and member resources are designed to get you operational fast.
