7 Things Wyomingites Know About I-80 Closures That Out-of-Staters Learn the Hard Way
Finding out the interstate is closed after you’ve already set out can ruin a trip fast.
Wyomingites who drive I-80 often know what to watch for, while visitors can get caught off guard.
Here’s what to know before your next drive across the state.
Note: This is general information, not legal advice. Closures, rules and penalties are subject to change, so check Wyoming 511 for current conditions.
1. Gates on Dry Pavement
An I-80 closure gate can come down where the pavement in front of you looks clear and dry.
The Wyoming Department of Transportation (WYDOT) says the trouble can be somewhere up ahead, including maintenance vehicles working in the roadway.
None of WYDOT’s rolling-closure gates are automated, according to Cowboy State Daily.
Crews lower each gate by hand.
Signs and other indications also warn you before you reach a gate.
Dry doesn’t mean open.
If you reach a gate, wait for the road to reopen, since drivers who go through risk becoming stranded or hurt.
2. Partial Closures
A partial closure on I-80 shuts the road to some vehicles or to one direction, so your vehicle or your route decides which side you’re on.
WYDOT defines it as a road closed to some but not all vehicles, or closed in only one direction.
The definitions list “no unnecessary travel” as a separate category: The road is open, but travel isn’t recommended because of hazardous driving conditions.
Visibility under 400 feet for any reason counts as reduced visibility.
The I-80 conditions page lists the interstate in segments from Evanston to Pine Bluffs, with Wamsutter, Rawlins, Elk Mountain, Arlington and Laramie among them, so you can check your stretch.
3. Light, High-Profile Closures
On March 14, 2025, WYDOT closed I-80 between Rawlins and Laramie to high-profile vehicles under 40,000 pounds gross vehicle weight because of extreme blow-over conditions.
A 43-mile stretch between Laramie and Cheyenne shut completely the same day, with crews estimating three to five hours to reopen it.
Recreational vehicles, moving vans, campers, small trailers and lightly loaded commercial vehicles count as light and high-profile.
Your camper counts.
Wyoming has closed highway sections to light, high-profile vehicles since 2011.
The weight-based wind closure system started in 2023.
If you’re close to a listed weight, you could still blow over.
What Wyoming Charges for Ignoring a Wind Closure
Wyoming’s closure law took effect July 1, 2024, and it makes ignoring a wind or weight-based closure a misdemeanor.
A first offense carries a $1,000 fine and up to 30 days in jail.
A conviction within three years of the first brings a $2,500 fine.
Wyoming Statute 31-5-229 can then treat the violation as reckless driving, which can bring driver licensing action.
4. Rolling Closures
Rolling closures on I-80 grow or shrink as conditions change.
Cowboy State Daily’s 2026 explainer gives an example: Hazardous weather near Elk Mountain could close the road between Laramie and Rawlins.
If conditions worsen, the closure could stretch east toward Cheyenne, west to Wamsutter, or both.
That’s a rolling closure.
The point is to help travelers without overtaxing the communities along the interstate.
The Wyoming Highway Patrol enforces rolling closures.
The typical ticket for driving on a closed road is around $1,000.
If you have a Wyoming driver license and live in Wyoming, you can apply for a Rolling Closure Authorization through WYDOT’s Wyoming Travel Authorization Program (W-TAP).
If you don’t, you can apply for WYDOT Authorized Travel authorizations only.
Participation in W-TAP doesn’t grant blanket approval to travel on any closed road.
The W-TAP FAQ says the milepost range on an authorization will likely change over time, and each change generates a new code.
Psst! How ready are you for an I-80 closure? Run through this checklist and see where you stand.
5. Elk Mountain and Arlington Closures
I-80 closures at Elk Mountain and Arlington both fall between Rawlins and Laramie on WYDOT’s segment list.
In February 2020, drifts several feet high near Elk Mountain helped close all lanes between Laramie and Rawlins.
As of 3 p.m. on a Sunday, WYDOT projected another 20 to 22 hours of closure.
That’s nearly a day.
With an estimate that long, you’ll want fuel and food before you reach that stretch.
Wind closed I-80 another way on March 12, 2026, after gusts of up to 109 mph.
I-80 in southeast Wyoming was closed to all trucks and trailers, regardless of weight.
If you were pulling a trailer that day, your weight didn’t matter.
As many as twelve blow overs were reported between Laramie and Arlington.
6. Closures Over 200 Miles Long
An I-80 closure on May 18, 2026, shut more than 200 miles of the interstate for much of the day.
Both directions between Rock Springs and Cheyenne were closed to all through traffic by 10:46 a.m. that Monday.
Many people stuck on I-80 all day expected to spend that night stuck there too.
As of Monday evening, the estimated reopening time between Rawlins and Laramie was between 6 and 8 on Tuesday morning.
That’s an overnight closure.
If you’re caught between those two towns, you could be waiting into Tuesday morning.
7. Wyoming 511 Closure Reports
Wyoming 511 reports I-80 closures by phone, website and app.
You can call 5-1-1, visit wyoroad.info or open the Wyoming 511 app.
WYDOT describes wyoroad.info as the authoritative source for current and accurate road conditions.
Its closures, advisories and restrictions page lists closures, chain law levels, closures to light, high-profile vehicles and links to National Weather Service forecasts.
The 511 resources also include interstate and non-interstate web cameras, variable speed limit information and a travel forecast map and video forecast.
For current wind speeds, the wind page sends you to wyoroad.info.
Monthly closure reports are also published for each route WYDOT maintains, so you can see what percentage of hours your route stayed closed.
The reports split commercial vehicles from passenger vehicles and leave out single-lane closures and construction.
Truck Lots for Closure Days
I-80 closure days got a new truck lot when Quealy Dome had its ribbon-cutting on September 20, 2023.
The lot, part of WYDOT’s I-80 Winter Freight Project, sits at the Quealy Dome exit, roughly 20 miles west of Laramie.
It has room for about 90 trucks.
Before the lot existed, truck drivers parked bumper-to-bumper along I-80 shoulders and on-ramps when storms forced rolling closures, according to Cowboy State Daily.
If you drive a truck on I-80, that lot gives you a designated place to wait during a storm closure.
The project also gave the Fort Steele Rest Area, at mile marker 228, a truck lot.
A $20 million federal grant helped pay for the project, which started in 2020.

The traditions that went away over the years never got that second chance.
