Since June 2025, Zion National Park has enforced strict size and weight limits on the Zion-Mount Carmel Highway. Vehicles exceeding 35 feet 9 inches in length, 7 feet 10 inches in width, 11 feet 4 inches in height, or 50,000 pounds are banned from the route. Previously, oversized vehicles could pass through the tunnel with a paid permit, but that option has been eliminated. The detour adds 30 to 90 minutes for travel between Bryce Canyon and Zion.
