Your destination determines the sensible highway: I-70 is the principal corridor for Summit County, Vail and Glenwood Springs, while US 40 over Berthoud Pass is the relevant route for Winter Park, Fraser and the Granby area. Grand Lake travelers generally use I-70 to Empire, US 40 to Granby and US 34 from there. Check live road conditions, weather and pass restrictions immediately before leaving; neither highway is a guaranteed congestion-free alternative.
Choose the route by destination first
I-70 and US 40 are not interchangeable approaches to one common mountain destination. They diverge near Empire and serve different valleys, passes and resort areas. Picking a road because it appears shorter on a map can put you on the wrong side of the Continental Divide or into a winter restriction that does not apply to the other route.

When I-70 is the better fit
Summit County
For the central mountain communities generally grouped as Summit County, I-70 is the direct corridor. It is the route designed to carry the large volume of Denver-area traffic toward the major ski and resort destinations in that valley. Switching to US 40 does not create a direct substitute for these places; it takes you toward Berthoud Pass and the Winter Park–Granby side of the mountains instead.

Vail and the western I-70 corridor
Vail and communities farther west remain I-70 destinations. A route planner may show local alternatives during an incident, but US 40 should not be presented as the normal Denver-to-Vail route. Check the I-70 corridor for crashes, lane restrictions, snow and traffic controls before you commit to the drive.
Glenwood Springs
Glenwood Springs is reached on I-70 through Glenwood Canyon. Canyon conditions can change the decision quickly, especially during a safety closure. CDOT publishes specific guidance for that situation rather than treating US 40 as a routine alternative. See CDOT’s Glenwood Canyon guidance for the agency’s current instructions.
When US 40 is the better fit
Winter Park and Fraser
US 40 over Berthoud Pass is the relevant approach from the I-70/Empire junction for Winter Park and Fraser. It serves a different destination set from the I-70 corridor, so the choice is primarily geographic rather than a promise of faster travel.

Granby is also reached from Empire on US 40. If your final stop is north or west of Granby, check the road beyond the pass as well; a clear Denver-to-Empire segment does not guarantee clear conditions all the way to your lodging or trailhead.
Grand Lake and Rocky Mountain National Park’s west side
The National Park Service lists a specific west-side approach: take I-70 to Exit 232 at Empire, continue on US 40 to Granby, then use US 34 to Grand Lake. Its directions page also warns that US 40 can close or operate under snow restrictions in winter. Review the route and seasonal conditions at the National Park Service directions page, which identifies a May 24, 2023 update; conditions can change after that page date.

Is US 40 a reliable way to avoid I-70 traffic?
No. US 40 is not a guaranteed delay-free bypass. Both roads can carry heavy weekend and holiday traffic, and each can be affected by snow, incidents or a crash at a bottleneck.
A CDOT advisory dated February 21, 2025, anticipated heavy travel on both the I-70 Mountain Corridor and US 40 over Berthoud Pass during a snowy, high-demand weekend. The advisory discussed tunnel metering and heavy demand for that particular event. It is useful evidence that both options can become busy at peak times, not a current forecast or a general statement that one route is normally slower. Read the event-specific notice at CDOT’s February 21, 2025 travel advisory.
There is no verified, current like-for-like comparison of mileage, normal travel time, fuel cost or toll cost between I-70 and US 40. Treat any universal “save X minutes” claim with skepticism unless it is tied to a particular date, destination, direction, weather pattern and traffic condition.
How to make the decision on the day you travel
- Enter the exact destination. Use the town, property or trailhead rather than a broad label such as “the mountains.” This prevents a route intended for Winter Park from being compared with one intended for Vail.
- Check the relevant highway in COtrip. Look for incidents, closures, lane restrictions and road-condition information on I-70 or US 40, and on US 34 if you are continuing to Grand Lake. CDOT’s I-70 page links to COtrip and corridor cameras.
- Review cameras near the critical segment. For I-70, inspect the corridor cameras, tunnels and major passes. For a US 40 trip, focus on Berthoud Pass and the approach from Empire. A camera image is a snapshot, so combine it with incident and weather information.
- Check the forecast for the pass, not only Denver. Conditions can be dry in the metro area and snowing at elevation. Look at the timing and intensity of the forecast along the entire route.
- Confirm winter equipment and legal requirements. Make sure the vehicle, tires and any traction devices comply with current Colorado rules and the vehicle manufacturer’s instructions. Requirements can change with conditions; do not assume that all-wheel drive alone satisfies a traction requirement.
- Allow a recovery option. If conditions deteriorate, know where you can safely stop, refuel or turn around. Do not improvise onto local or forest roads that are not part of CDOT’s recommended route.
- Recheck immediately before departure. CDOT identifies COtrip and 511 as current road and weather information sources. A morning check can be obsolete by the time a storm reaches the pass.
Use CDOT’s winter-driving guidance for vehicle preparation, traction and chain-law links, COtrip access and 511 instructions: CDOT winter driving.
Winter driving: the risks are different, not absent
US 40 and Berthoud Pass
The National Park Service explicitly cautions that US 40 may close or have snow restrictions in winter. Berthoud Pass exposure, blowing snow and changing visibility can make the route unsuitable for a vehicle or driver that is not prepared for mountain conditions. Check the pass status before leaving Empire and again during the trip if weather is changing.

I-70’s mountain-corridor hazards
I-70 is a major highway, but its scale does not remove mountain-driving risks. Steep grades, tunnels, weather, crashes and heavy demand can produce long delays or controls. CDOT’s description of the corridor as challenging is a practical warning to plan for changing conditions rather than a statement that the highway is unsafe in ordinary use.
Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Repair Windows errors before they cause bigger problems3Scan for outdated or missing drivers - takes under a minuteTraction devices, tires and vehicle capability
CDOT’s winter resource links to passenger-vehicle traction and chain laws. The applicable requirement depends on current conditions and the vehicle. Check the law, the tire markings and the owner’s manual before a storm, and practice installing approved devices when conditions are safe. Do not buy or carry a device without confirming its fit for your tire size, wheel well clearance and vehicle manufacturer restrictions.
What happens if Glenwood Canyon closes?
Glenwood Canyon closures require a different decision from the ordinary I-70-versus-US-40 comparison. CDOT recommends a northern alternate using CO 9, US 40 and CO 13 when a safety closure is expected to last longer than one hour. The agency says that detour adds approximately two and a half hours compared with continuing on I-70 through Glenwood Canyon.
That figure applies only to the qualifying closure scenario described by CDOT. It is not a normal Denver-to-the-mountains travel-time estimate and does not mean US 40 is a routine shortcut to Glenwood Springs or other I-70 destinations. Follow CDOT’s directions during an actual closure; avoid inventing a route through unsuitable local or forest roads. The official instructions are at CDOT’s Glenwood Canyon page.
Driving versus seasonal public transportation
You do not always need to drive. The Denver Regional Council of Governments lists seasonal mountain transportation, including Snowstang bus service to several ski areas and the Winter Park Express train from Denver Union Station to Winter Park. It also lists Bustang and Pegasus services for portions of the mountain corridor.

These services are seasonal, and operating dates, departure times, reservations and fares can change. Verify the intended travel date with the operator through the information collected by DRCOG’s mountain transportation page. Transit can remove the need to handle a snowy pass yourself, but you still need a plan for the final connection from the station or bus stop to your lodging.

“I am going to a Summit County ski area.”
Start with I-70. Check the corridor, tunnel and pass conditions, then make a departure decision based on the live information. US 40 is not a like-for-like alternate for Summit County.
“I am staying in Winter Park or Fraser.”
Plan on I-70 to Empire and US 40 over Berthoud Pass. Check US 40 specifically; an I-70 report alone does not tell you whether the final mountain segment is open or restricted.
“I am going to Grand Lake.”
Use the National Park Service’s sequence— I-70 to Exit 232 at Empire, US 40 to Granby and US 34 to Grand Lake—then check all three highways and any applicable park information. Winter restrictions on US 40 can change whether that approach is practical.
“I am going to Vail or Glenwood Springs.”
Use I-70 as the normal corridor. For Glenwood Springs, pay particular attention to Glenwood Canyon status. If CDOT activates its northern detour for a qualifying closure, follow that official route and budget the stated additional time.

“I just want to reach the mountains and have not chosen a town.”
Choose the destination first. “The mountains” covers multiple valleys and highways; a route comparison without a town cannot produce a meaningful answer.
Common mistakes and how to avoid them
- Choosing by map distance alone: A short-looking line may cross a restricted pass or end far from the intended destination. Match the highway to the town.
- Treating a historical advisory as a live report: The February 21, 2025 CDOT notice describes one snowy weekend. It cannot predict today’s traffic.
- Checking only Denver weather: Mountain passes can have snow, ice or wind when the city is clear. Read the route-specific forecast.
- Assuming US 40 is always quieter: Peak demand can affect Berthoud Pass as well as I-70.
- Assuming AWD solves every winter requirement: Traction laws, tires and approved devices still depend on conditions and the vehicle. Follow CDOT and the owner’s manual.
- Using an unofficial canyon bypass: During a Glenwood Canyon closure, use CDOT’s designated detour and do not improvise on roads not intended for through traffic.
- Relying on a stale screenshot: Conditions and closures change. Use COtrip, cameras and 511 immediately before departure.
A compact pre-departure checklist
- Destination entered precisely, including the final town or park entrance.
- Correct corridor checked in COtrip for incidents, closures and restrictions.
- Pass and mountain forecast reviewed for the expected travel period.
- CDOT cameras checked where available.
- Tires, fuel, windshield washer fluid, lights and emergency supplies inspected.
- Traction or chain equipment confirmed compatible and legally usable for the vehicle.
- Backup plan identified if the selected highway closes.
- 511 or COtrip rechecked immediately before leaving Denver.
Frequently asked questions
Can I take US 40 instead of I-70 to Vail?
US 40 is not the normal direct route to Vail. Vail is served by the I-70 corridor; use CDOT’s live information to manage conditions on that highway.
Does US 40 always have less traffic than I-70?
No. Both corridors can experience heavy demand. CDOT’s February 21, 2025 advisory documented expected heavy travel on I-70 and US 40 during the same snowy holiday weekend, but that event-specific notice is not a general traffic forecast.

What should I do if my navigation app sends me onto a small mountain road?
Do not follow an improvised shortcut simply to avoid a delay. Check COtrip and CDOT’s official instructions, especially during a closure, and remain on designated roads suitable for your vehicle and conditions.
Where can I get current road information?
CDOT directs travelers to COtrip, I-70 cameras and 511 for current road and weather information. Use those sources immediately before departure and again if conditions change.
