Landslide closes Colorado’s Loveland Pass indefinitely

Colorado’s Loveland Pass (U.S. 6) was shut down at 5:25 a.m. on Sunday, June 15, 2025. A massive landslide struck near mile marker 226. The landslide measures approximately 100 feet wide and 15–20 feet deep. The slide buried both traffic lanes under mud and rock.

Cleanup? Not yet

CDOT reports that the slide zone is “still actively moving.” It is too dangerous to begin efforts to clear the debris. CDOT spokesperson Austyn Dineen cautions that this is likely to be an “extended closure.”

RVers can expect traffic holds at the Eisenhower-Johnson Memorial Tunnels. Traffic will be stopped at the top of each hour to allow hazmat vehicles to pass through.

While no firm timetable has been released, officials describe the delay as prolonged, and no reopening date has been set.

What the Loveland Pass landslide means for RVers

Since Loveland Pass is a key travel route, its closure most certainly will disrupt many plans. Here are safe, practical alternatives:

• Take I‑70 through the Eisenhower–Johnson Tunnels. The tunnels now handle all vehicular traffic. RVs are allowed, and trucks with hazardous materials may pass during scheduled window times. CDOT will manage tunnel flow accordingly.

• Stay on I‑70 East/West and enter the tunnel near Silverthorne or Idaho Springs depending on your direction of travel.

• Arapahoe Basin access. The ski area remains accessible from the western side via I‑70 and U.S. 6 west of the slide zone. Note that access is completely cut off from the east (Loveland Ski Area side).

Travel tips

• Monitor CDOT alerts (social media, highway cams, web updates) for signs of movement or reopening.

• Expect delays and rerouting. The tunnel route might face heavier than normal traffic as all vehicles converge there.

• Plan alternate stops: With Loveland Pass closed, popular trails and picnic spots along the route aren’t accessible. Check with your campground to see if access remains available.

• Be patient and adjust your itinerary accordingly.

Stay safe!
