Shipping Heavy Equipment from Denver, CO to Salt Lake City, UT

Route Overview: Denver to Salt Lake City

The standard heavy haul route from Denver, CO to Salt Lake City, UT runs approximately 525 miles. The primary corridor follows I-70 west from Denver through the Eisenhower Tunnel (elevation 11,013 ft) and Vail Pass, then continues through Grand Junction before connecting to I-15 north into Salt Lake City. An alternate southern route via US-50 through Gunnison and Montrose adds mileage but avoids the Eisenhower Tunnel's height and weight restrictions. Transit time for heavy equipment is typically 2 to 3 days, accounting for mountain driving speeds, permit travel windows, and mandatory rest stops.

Critical Infrastructure: Eisenhower Tunnel

The Eisenhower-Johnson Memorial Tunnel on I-70 is a critical chokepoint for oversize loads. The tunnel has a posted height limit of 13 ft 6 in and a width restriction of 14 ft for oversize loads. Loads exceeding these dimensions must use the alternate Loveland Pass route (US-6), which adds approximately 30 minutes but has no tunnel restrictions. However, Loveland Pass has steep grades (up to 11.9%) and sharp switchbacks that require experienced mountain drivers. Loads over 14 ft wide are typically prohibited on Loveland Pass as well and must route south via US-50 through Monarch Pass.

Permit Requirements

Colorado permits are issued by CDOT. The state has strict oversize regulations, particularly for mountain routes: loads over 10 ft wide require a pilot car on I-70 west of Denver, and loads over 14 ft wide require two escorts. Utah permits are issued by UDOT; the state's legal weight limit is 80,000 lbs GVW, and oversize loads require permits for widths over 8.5 ft. Both states restrict oversize movement during adverse weather — Colorado can issue travel bans on I-70 mountain segments during winter storms, sometimes lasting 12 to 48 hours.

Trailer Selection

• RGN (Removable Gooseneck): Best for tall equipment. Note that the Eisenhower Tunnel's 13.5 ft height limit may require routing via Loveland Pass for loads over 13 ft tall on an RGN.
• Lowboy: Preferred for heavy mining equipment, large compactors, and crane components. Lower deck height helps manage mountain clearances.
• Step Deck: Good for mid-size equipment under 10 ft tall. Avoids some oversize permit triggers on Colorado mountain routes.
• Multi-Axle Configurations: Heavy loads over 100,000 lbs may require 5-axle or 7-axle configurations to distribute weight on mountain grades and comply with bridge weight limits.

Key Equipment Moved on This Lane

The Denver-Salt Lake City corridor serves Colorado's active mining and energy sectors as well as Utah's construction and infrastructure markets. Common loads include mining haul trucks, drilling rigs, large excavators, and crane components moving between Colorado's mountain mining operations and Utah's Wasatch Front construction projects. Equipment dealers in Denver and Salt Lake City also regularly exchange inventory, and auction buyers from both markets ship purchases across this corridor.

Seasonal Considerations

Winter is the most significant operational challenge on this route. I-70 through the mountains is subject to frequent closures from November through April due to snow, ice, and avalanche control. CDOT can close I-70 at any time with little notice; carriers must monitor CDOT's COtrip system and build contingency days into mountain haul schedules. Spring brings snowmelt and potential mudslides on alternate routes. Summer is the most reliable season, though afternoon thunderstorms in the Rockies can create brief but intense hazards. Fall (September–October) offers good weather windows before winter sets in.
