Interstate 70 is a critical east-west corridor stretching over 2,100 miles from Utah to Maryland. In Colorado, it serves as a vital link connecting Denver with mountain towns, ski resorts, and the Western Slope. The highway's segment through the Rocky Mountains is renowned for its engineering marvels, including the Eisenhower-Johnson Memorial Tunnels — the highest vehicular tunnels in the United States.

Driving along Colorado's I-70 offers breathtaking mountain views and connects travelers to some of the state's most popular destinations. However, frequent closures can turn a scenic journey into a challenging ordeal. Understanding when and why these closures occur is crucial for planning a smooth trip. In this guide, we'll connect you with where to look for the latest updates, and help you understand more about the frequent closures and delays.

Where to Find Real-Time Updates on I-70 Closures

Staying informed is key to navigating I-70 successfully. If you’re stuck wondering why there is a closure, it’s a good idea to get real-time updates from a reliable source. Utilize these resources for the latest information:

  • CDOT Travel Information: Offers real-time updates on road conditions, closures, and traffic cameras.

  • CDOT Mobile App: Available for iOS and Android, providing personalized travel alerts.

  • Colorado State Patrol (CSP): Provides updates on accidents and road safety tips. Follow their social media accounts for timely information.

  • Weather Forecasts: Check the National Weather Service for current weather conditions and forecasts along I-70.

Common Reasons for I-70 Closures

Weather-Related Closures

Colorado's mountainous terrain and high elevations make I-70 particularly susceptible to severe weather conditions. Heavy snowfall, icy roads, and blizzards can lead to hazardous driving situations. Winter storms can dump several feet of snow in a short period, making the roadway impassable. The Colorado Department of Transportation (CDOT) may close sections of I-70 to clear snow and ensure driver safety. Additionally, strong winds can cause whiteout conditions and increase the risk of accidents, prompting temporary closures.

Accidents and Emergencies

Accidents are a common cause of unexpected closures on I-70. High traffic volumes, especially during ski season, increase the likelihood of vehicle collisions. Closure durations depend on the severity of the accident and the time required for emergency response and cleanup. Incidents involving hazardous materials necessitate immediate closures to protect public health and the environment.

Construction and Maintenance

Ongoing efforts to maintain and improve I-70 infrastructure can lead to planned closures. Construction activities may require lane reductions or full closures during off-peak hours. The Eisenhower Tunnel undergoes regular maintenance to ensure operational safety, which can result in scheduled closures.

Avalanche Control Near the Eisenhower Tunnel

The areas surrounding the Eisenhower Tunnel are prone to avalanches due to steep slopes and heavy snowfall. CDOT conducts proactive avalanche control operations using explosives to trigger controlled slides. During these operations, I-70 is temporarily closed to traffic.

Hazardous Materials Regulations and Eisenhower Tunnel Closures

The Eisenhower Tunnel has strict regulations regarding the transportation of hazardous materials. Generally, vehicles carrying hazardous materials are prohibited from passing through the tunnel due to safety concerns. Instead, they are directed to use the alternative route over Loveland Pass via U.S. Highway 6. However, when Loveland Pass is closed — often due to adverse weather conditions — CDOT may implement a "hazmat convoy" through the Eisenhower Tunnel. During a hazmat convoy, the tunnel is temporarily closed to regular traffic to allow a controlled group of hazardous materials vehicles to pass through safely. These convoys are carefully coordinated and can lead to intermittent closures, usually lasting about 15 minutes, but potentially causing longer delays depending on traffic.

How Long Do I70 Closures Usually Last?

According to CDOT, the winter season accounts for the majority of weather-related closures. On average, I-70 experiences about 30 full or partial closures each winter between November and April. Closure times vary widely, from brief 15-minute stoppages for avalanche control to multi-hour closures during severe storms or major accidents. The Eisenhower Tunnel is closed approximately 25 times per year due to adverse weather or maintenance needs, affecting both eastbound and westbound traffic.

Tips for Navigating I-70 Safely

  • Plan Ahead: Before hitting the road, check the latest road conditions and weather forecasts. Knowing what to expect can help you avoid unexpected delays.

  • Prepare Your Vehicle: Ensure your car is winter-ready with proper tires, functioning wipers, and an emergency kit. Adequate vehicle preparation is crucial for safe travel in harsh conditions. Read more on winter safety from CDOT.

  • Traction and Chain Laws: Colorado enforces traction and chain laws during severe weather. Non-compliance can result in fines up to $650. Familiarize yourself with these regulations to avoid penalties.

  • Drive Cautiously: Adjust your speed according to road conditions and maintain a safe following distance. Icy roads require slower speeds and gentle braking to prevent skidding.
