How to Navigate the Zion-Mount Carmel Highway Large Vehicle Restrictions
Zion-Mount Carmel Highway is closed to large vehicles. Explore some alternative scenic routes to reach Zion National Park.
We’ve all had our share of challenges on a road trip: Flat tires, cracked axles, maybe an RV refrigerator door that didn’t latch properly, and a deep turn sends milk soaring across the floor. Sometimes a trip hits a sour note. . . or smell. With RVing and large vehicles, there are events you can’t plan for.
Fortunately, here’s one you can. The historic Zion-Mount Carmel Highway and Tunnel are closed to large vehicles. If your road-trip involves Zion National Park, the Mount Carmel Highway is likely part of your plan, so you will want to keep reading.
What are the Restrictions?
The Zion-Mount Carmel Highway, a 10.7-mile stretch carved into red rock in 1930, wasn’t built for today’s oversized rigs. Modern RVs, tour buses, and trailers often struggle with the tight curves and narrow bridges.
On June 7, 2026, vehicles longer than 35 feet, 9 inches, wider than 7 feet, 10 inches, taller than 11 feet, 4 inches, or weighing over 50,000 pounds are no longer permitted on the Zion-Mount Carmel Highway between Canyon Junction and the Zion National Park East Entrance.
These restrictions mean many Class A motorhomes and long fifth-wheels, icons of RVing, will need new routes to get into the park. This change isn’t meant to keep you out; it’s meant to keep everyone safe and to protect historic infrastructure for generations to come.
You’re Not Blocked — Just Rerouted
You might be thinking, “Well, how will we get to Zion National Park?” The answer is simple: Enter through Springdale, Utah.
Instead of cutting straight through the Zion-Mount Carmel corridor, approach Zion from the west (via SR-9 through Springdale). The SR-9 corridor is open to large vehicles and is the most direct access to the heart of the park.

Detours Aren’t Delays
Adaptability is a vital characteristic for road travel, and we have a couple work arounds to avoid the Zion-Mount Carmel Highway while still enjoying what the open road has to offer.
Each route offers a different rhythm. Some climb through an alpine forest. Others roll across the open desert. All deliver you to Zion National Park without going through the tunnel.
The National Park Service estimates these alternate itineraries can add 10 to 45 minutes of drive time, depending on the option you choose.
Coming from Bryce Canyon National Park

Park for free at the Zion Corridor Park & Ride in Virgin, Utah, then board the shuttle (SunTran or the Zion White Bison Shuttle) into Springdale.
