Travel Forecast & Tips
Fortunately, I-70 is congestion free the majority of the time and traffic is quite predictable, weather and accidents withstanding. Plan to avoid peak travel times, and enjoy a delay-free trip along I-70. Our weekend travel forecast is updated every Thursday afternoon.
Weekend Travel Forecast
The weather forecast is for light to moderate snow all along the mountain corridor on Friday, on and off snow Saturday morning, with partly cloudy skies Saturday afternoon and Sunday. Traffic metering is possible eastbound on Saturday or Sunday afternoons/evenings which means delays at the Eisenhower Tunnel. Metering is done entirely for safety reasons and is not a congestion management tool. Metering avoids a situation where traffic would be at a standstill in the tunnel, making emergency services access virtually impossible.
Friday WB – Light to moderate traffic is possible from 4:00-9:00 p.m. Weather will likely be a factor.
Saturday WB – Moderate to heavy traffic is likely from 6:30 a.m.-11:30 a.m. with peak delays occurring around 8:00 a.m. Weather could be a factor.
Saturday EB- The volume of traffic is not expected to be significant, but your best bet is to avoid the 2:00-6:00 p.m. timeframe.
Sunday WB – Traffic is unlikely.
Sunday EB –Moderate to heavy traffic is possible. The past two years on this weekend, volumes have not been great, but to play it safe, Change your Peak Time and avoid travel between 2:00 pm and 7:00 pm.

Tips for I-70 mountain travel
- Avoid the Peak Travel Times. If heading eastbound on Saturday or Sunday, plan to leave the mountains after 7:00 p.m. Check the weekend and holiday Travel Forecast.
- Check the road and traffic conditions before you travel.
- Check out the Deals local businesses offer to help you avoid peak travel times.
- Spend a Sunday night in the mountains and head to work or school early Monday morning.
- Create or join a carpool.
- Consider taking a bus or van to the mountains and leave the driving to someone else.
Winter Traffic Patterns
(early Dec-mid April. Based on historical data.)
Friday Westbound - Light to moderate traffic from about 4:00-9:00 p.m.
Saturday and Sunday Westbound - Moderate traffic from about 6:30 a.m. to 11:00 a.m. with the peak around 7:30-8:00 a.m. Sunday morning WB traffic is typically lighter than Saturday morning, or non existent.
Saturday EB - Traffic builds around 2:30 p.m., peaks around 4:00-5:00 and drops dramatically after 7:00 p.m. Expect heavy congestion.
Sunday EB - I-70 starts to fill up earlier than it does on Saturday, as early as 1:00 p.m. Traffic peaks around 4:00-5:00 and drops off soon after 7:00 pm. Expect very heavy traffic.
Other factors: Metering - Traffic metering goes into effect during very high volume times at the Johnson/Eisenhower Tunnels. This process involves controlling the flow of traffic eastbound into the Eisenhower Tunnel, so traffic does not back up in the tunnel.
Holiday Weekends – when a national holiday falls on a Monday, you can count on Monday afternoon EB traffic to mimic a typical Sunday pattern, but with potentially more volume. On the flip side, the Sunday of holiday weekends tends to have minimal congestion.
Weather & Accidents - can escalate the level and duration of congestion dramatically.
