Heavy haul in Utah
Utah heavy haul is shaped by geography. I-15 runs the length of the state from St. George to the Idaho line, I-80 comes in from Wendover and climbs out through Parleys Canyon toward Wyoming, I-84 splits off toward Idaho, and I-70 starts at I-15 and runs east to Colorado. Most of those meet in the Salt Lake, Davis, Weber and Utah County corridor, which is exactly where UDOT's rush-hour curfew applies.
I drove trucks before I ever brokered a load, I have spent more than 15 years in freight, and I have pulled oversize permits myself. So when a Utah load comes in, I am not reading the rules for the first time. I am looking for the part of the move that will actually bite: the escort trigger you are an inch over, the curfew that eats your window, the structure that cannot take the weight. Every load runs on CRST's asset-based network, with CRST's authority, insurance and compliance behind it, and one person accountable for it: me.
The numbers
Over any of these needs a UDOT permit before entering Utah (except at the St. George, Echo and Wendover ports):
| Dimension | Utah legal limit | Over that means |
|---|---|---|
| Width | 8 ft 6 in | Permit. One pilot over 12 ft on secondary highways or 14 ft on divided interstates. |
| Height | 14 ft | Permit. Over 16 ft needs two pilots; over 17 ft 6 in needs a police escort. |
| Length | Single unit 45 ft; combinations per R909-2-4 | Permit. One pilot over 105 ft (secondary) or 120 ft (divided). |
| Gross weight | 80,000 lb | Overweight permit; over 300,000 lb is a superload. |

Roads
The spine. Southern Utah is open; from Utah County north through Salt Lake, Davis and Weber counties, the curfew sets your schedule.
Flat across the salt flats, then Salt Lake, then a steep climb up Parleys Canyon and on through Echo toward Evanston.
Starts at I-15 and runs east through very remote country to Green River and Grand Junction, Colorado. Plan fuel and staging carefully on long wide-load days.
I-84 links Ogden to Idaho and Echo to I-80. US-6 over Soldier Summit connects Spanish Fork to Price and eastern Utah, and is a two-lane route with secondary-highway escort rules.

Why Vector
Utah rewards planning. A load that hits Salt Lake at 3:45 PM sits until 6. A superload submitted late waits up to two weeks. We build Utah schedules backward from the curfew and the permit lead time, so your load arrives when the crane does.
Typical Utah move: an 11 ft wide excavator, Salt Lake City to St. George on I-15. UDOT single-trip permit, no pilot at that width on the divided interstate, and a departure timed to clear the Wasatch Front curfew.
