How our tow trucks get from Boulder to Longmont
Longmont is one of our longer runs, 15 to 16 miles by road and approximate, and nearly all of it is CO 119, the Diagonal Highway. Our 24-hour dispatch out of Boulder sends the truck northeast past the Niwot Road intersection, and at the Longmont end the expressway becomes Ken Pratt Boulevard and crosses US 287, which is Main Street through the middle of the city.
That distance is why a Longmont arrival window runs longer than a Louisville one; we give it on the call, not in print. A car near CO 66 on the north side, or out east toward I-25, adds road past the end of the Diagonal, and snow or the Hover Street detour adds time. The quote is the same at 3 a.m. as at noon.
Longmont also crosses a county line. The city lies in Boulder and Weld counties, about 30 square miles in all, and its east side reaches into western Weld County toward I-25. For us both sides are the same job; the county line changes which sheriff patrols the unincorporated land around the city, not the truck we send.
Where Longmont tow calls come from: the Diagonal, Hover Street, Main Street and I-25
On the Diagonal itself, CDOT has counted the cost: 929 vehicle crashes on CO 119 between Boulder and Longmont from 2015 to 2019, with 446 injuries and 3 deaths. CDOT is now working on about ten miles of it, mile points 44.5 to 54.5 between Foothills Parkway and Hover Street, adding a commuter bikeway and bus rapid transit, with completion scheduled for spring 2027. Until then, expect night lane closures in the work zone, like the ones CDOT has scheduled at Jay Road.
Hover Street
CDOT's regional transportation director calls CO 119 and Hover Street the busiest intersection in Longmont, and CDOT is building a bridge there to carry southwest-bound CO 119 over Hover. Every left turn at the intersection has been closed since early September 2026, and the city says the closures stay until the project is complete in 2027. Coming off the Diagonal toward northbound Hover, the detour turns north on Airport Road before the intersection, so if you stop near it, tell us which side of Hover you are on and your direction.
Main Street, Ken Pratt, CO 66 and I-25
- US 287 is Main Street, running north-south through the center of Longmont and crossing CO 119 on the way.
- CO 119 becomes Ken Pratt Boulevard south of downtown, then an expressway east to a diamond interchange at I-25 exit 240, about 5 miles out, on the Weld County side.
- CO 66 follows the north edge of the city, meets US 287 there and reaches I-25 at exit 243 near Mead; its west end is at US 36 just southeast of Lyons.
If the car still rolls, get it onto the shoulder with the hazards on and everyone out on the side away from traffic. Colorado's move-over law, C.R.S. 42-4-705, covers any stopped vehicle showing hazard lights; on a road posted 45 mph or faster, a driver who cannot change lanes is presumed safe at 20 mph under the limit. Not every driver complies, so wait well off the pavement, and call 911 first if anyone is hurt.
Snow on Longmont's side streets, and when the flatbed comes
Upslope storms reach Longmont too: in the March 13-14, 2021 storm the National Weather Service logged 25.5 inches three miles northeast of the city. Longmont keeps 356 miles of centerline roadway and plows 146 of them in its annual snow and ice program: arterials for commuters and emergency access, and collector streets that reach schools and bus routes.
Residential streets are not part of that program. Longmont launches its Residential Snow Plow Program only in severe storms, and the city warns that those passes leave rows of snow four to six feet high around cars and driveways. A car high-centered on packed snow in a side street, or nosed into one of those rows, needs a winch-out on an unplowed Longmont street before anyone decides whether it needs a tow.
In a storm the drivetrain matters as much as the address. All-wheel-drive SUVs, four-wheel-drive pickups and electric cars ride with all four wheels off the road, on the truck AAA singles out as ideal for all-wheel and four-wheel drive; the flatbed rules for AWD and electric cars explain why.

Who orders a tow in Longmont, and how to find a towed car
Police and fire in Longmont belong to the city's Public Safety Department, and its Longmont Emergency Communications Center takes non-emergency calls around the clock at 303-651-8501. That is the first call if your car is missing from a Longmont street: the PUC's advice after any law enforcement tow is to ask the agency that ordered it which carrier it sent. Police records are at the Safety and Justice Center, 225 Kimbark Street, 303-651-8502, weekdays from 8 a.m. to 5 p.m.
Longmont's street clock is short. Under section 11.12.040 of the municipal code, a vehicle left on a public street or public property for 48 hours or longer may be treated as abandoned; staff mark the tires, tag the car, and come back to tow it if it has not moved. A car that died at a Longmont curb is worth moving before that second visit.
Past the city line the county takes over: the Boulder County Sheriff on the Boulder County side, through the non-emergency line 303-441-4444, and the Weld County Sheriff's Office, which covers all unincorporated Weld County, at 970-356-4015. After a tow from an apartment complex lot, the PUC's advice is to find the tow company's sign on the property and call the number on it. Colorado's towing rules, 4 CCR 723-6, cap what those nonconsensual tows can cost; how the capped tows differ from ours is on the cost page.
What we ask on a Longmont call, and which truck comes
On a Longmont call, the first of our four questions needs more detail than in town:
- Where, exactly. On the Diagonal, your direction and the last intersection you passed - Jay Road, 63rd Street, Niwot Road or Airport Road; inside Longmont, the street and the nearest corner; on I-25, the exit.
- What it is. Year, make, model and drivetrain - all-wheel, four-wheel, electric or hybrid.
- What happened. Crash, breakdown, snow, a flat, a dead battery or locked keys.
- Where it goes. A Longmont shop, a Boulder dealer, your driveway, or farther, by the mile.
Front-wheel-drive cars ride a wheel-lift, the smaller truck for a tight driveway or a parking garage. We are light-duty - cars, SUVs, pickups, vans and motorcycles - so a loaded box truck or a big motorhome is past our rating, and we say so on the phone. A breakdown or crash on the Diagonal after dark gets a night tow off the Diagonal on daytime terms.
Towing near Longmont: Niwot, Lafayette, Lyons and Broomfield
We cover Niwot and the rest of the Diagonal on the way. US 287 runs south from Longmont to Lafayette, 11 miles from Boulder, where towing in Lafayette along US 287 works the same way; Lyons sits near the west end of CO 66. Broomfield, on US 36 and I-25, is on the Broomfield towing page.
Frequently asked
How far is Longmont from Boulder by tow truck?
About 15 to 16 miles by road, nearly all on CO 119, the Diagonal Highway, which becomes Ken Pratt Boulevard at the Longmont end. We quote a Longmont tow on that distance plus the miles to wherever the car is going, and give the arrival window on the call.
Where do I call to find a car towed in Longmont?
Call 303-651-8501, the Longmont Emergency Communications Center's non-emergency line, which answers around the clock, and ask whether police ordered the tow and which carrier has the car. After a tow from an apartment complex lot, Colorado's PUC advises finding the tow company's sign on the property and calling the number on it.
Does Longmont plow residential streets?
Not in its regular program: the city plows 146 of its 356 centerline miles each winter and launches its Residential Snow Plow Program only in severe storms. If a car is stuck on an unplowed side street, a winch-out usually gets it moving without a tow.
How long can a car stay parked on a Longmont street?
Under section 11.12.040 of Longmont's municipal code, a vehicle left on a public street or public property for 48 hours or longer may be treated as abandoned. Staff mark the tires and tag the car before towing it, so a broken-down car should be moved before then.
Can you take an all-wheel-drive car or an EV from Longmont to a Boulder dealer?
Yes. We carry all-wheel-drive, four-wheel-drive and electric vehicles on a flatbed and quote the run by distance before the truck leaves. Mention the drivetrain when you call, and the flatbed is the truck that shows up.
