Interstate 80 Exit List

Most of the information contained herein is derived from the Wyoming Department of Transportation 1997 Wyoming Reference Marker System. That guide lists highways by their state inventory control number. Since these inventory numbers are not featured on the highways, this list is designed to provide mileposting information for individual, signed highways.

The following table lists all of the major towns, geographical features, highway junctions, and points of interests along the route. Each of the signed routes (including multiplexes) are shown in the first column for each entry. The second column shows the actual milepost marker as found on the highway; note that the mileposts rarely reset at zero at the start of new highways. In the third column is the description of the town or geographical feature. "CL" refers to "City" or "Corporate" Limits. The fourth column lists the state control inventory route, and the fifth column provides the distance between each geographical feature. If there are multiple features that require several lines to explain, then the distance in this column would be zero. Finally, the last column shows the cumulative mileage of the route. The last, bold-faced number in the column provides the total mileage for the signed route.

Thanks to James Lin and C.C. Slater for the use of their highway markers in this table.

EAST NORTH
Exit 197 Wyoming Port of Entry (EASTBOUND ONLY) As you travel east along , you will start to see Wyoming DOT-issued signs warning motorists about the upcoming Port of Entry four miles before the state line. These signs indicate which vehicles need to stop at the Port.
Milepost 0 Welcome to Wyoming and Uinta County!
Exit 1 Old Utah Port of Entry - the new one is located some miles west of here (WESTBOUND ONLY) SPEED LIMIT 75 All commercial and some private trucks must stop at the Port of Entry. The Wyoming facility was finished in 1994; it is designed to handle significantly more trucks than it could before the facility is upgraded.
Exit 3 BUSINESS TO NORTH Harrison Drive Evanston West Right after the Port of Entry, you will see "NORTH "signs for the first time. Although Utah doesn't admit it, is tangent with U.S. 40 from Heber City to Silver Creek Junction and with from Silver Creek Junction to east of Evanston.

Exit 5 NORTH SOUTH Front Street Mirror Lake Scenic Byway High Uintas Wyoming State Hospital This exit is the most direct route into downtown Evanston. It also provides access to Wal-Mart, McDonalds, and the whole array of franchise facilities ... but the state mental health facility is right on the other side of the freeway from the franchises. Although Exit 5 now provides direct access into Evanston, this interchange was not part of the Evanston exits as recently as 1985. That middle exit was opened in spring or summer 1986. On the westbound "Evanston NEXT 3 EXITS" sign, you can see the green-out where the "3" was pasted over the "2." Before, that you could only get to and by using Exit 3 or Exit 6, and driving through Central Evanston via. This is one of the reasons why those two exits are also signed as TO , even though they are not the most direct route to .
Exit 6 BUSINESS TO NORTH Harrison Drive Evanston STATE OF WYOMING INFORMATION CENTER AND REST AREA

Uinta County Route 180 Bear River State Park
For eastbound travelers, Old Evanston Road (CR-180) is the original route of Historic SOUTH between exits 10 and 30.
Exit 10 Painter Road The Old Eagle Rock Ski Area, which is no longer in operation, is near this exit.
Exit 15 Divide Road Three Sisters The Three Sisters are the three hills that you will traverse between exits 15 and 30. Heading westbound, the first sister is right after Exit 15.
Exit 18 NORTH Uinta County Route 181 SOUTH Kemmerer Piedmont Yellowstone-Grand Teton National Parks via NORTH
Uinta County Route 181 connects Historic with Historic SOUTH (Uinta County Route 180).
The exit marks the low point between the first two Sisters if you're heading eastbound (it's between the second two if you're heading westbound).
EAST
Exit 21 Coal Road Between exits 18 and 21, westbound travelers will go up Toms Draw and then descend into the Piedmont Valley. Trucks should crank up in preparation for the last sister, right after Exit 24.
Exit 23A/23 Bar Hat Road
Exit 23B/24 Uinta County Route 141 Uinta County Route 173 Leroy Road Piedmont Road Heading westbound, you will see the Bigelow Bench, which will take you to over 6000 feet elevation. Heading eastbound, you are leaving the Green River Basin. The terrain will be much hillier as you head toward Evanston and Utah.
Exit 28 Uinta County Route 207 French Road PARKING AREA
Exit 30 Uinta County Route 202 Bigelow Road (also Bigelow Bench Road) Westbound travelers may exit here for historic SOUTH along Uinta County Route 180 between exits 30 and 10.
Exit 33 Uinta County Route 230 Union Road You are now entering the Bridger Valley, named for the famed mountaineer, Jim Bridger.
Exit 34 BUSINESS LOOP Fort Bridger Urie Lyman Business Loop through the Bridger Valley communities of Fort Bridger, Urie, and Lyman is the longest Interstate business loop in the state at approximately 15 miles, between exits 34 and 48. The eastbound and westbound signs announcing the business loop actually read LOOP, which is unlike any other business loop sign in the state. Most times, Wyoming DOT writes the word "BUSINESS" above the business loop shield. There is no cardinal direction indicator (i.e., East or West).
Fort Bridger State Historic Site via Business Loop. Follow for Historic SOUTH. For westbound traffic, this is a good place to stop before heading onto Evanston. If the weather's bad, don't continue west, since the freeway traverses three large hills locally known as the "Three Sisters." Tire chains and snow tires may be necessary in winter.
Exit 39 NORTH SOUTH Carter Mountain View Flaming Gorge National Recreation Area via
Exit 41 SOUTH Lyman REST AREA
The Lyman Rest Area (exit 41) is a solar-powered rest area. There is a big display there that explains how the water is heated by the panels on the roof. This is a common design for the smaller rest areas across the state of Wyoming and also some of the larger ones too. Rest area buildings are also designed to face the sun and to avoid the wind with sloping roofs. For that reason, Wyoming rest areas are considered state-of-the-art in energy efficiency, but they are also few and far between. A program is under way to build more rest areas along Interstate, U.S., and Primary State highways.
On a more disturbing note, this is the only rest area in the state where I have seen extensive graffiti in and around the building.
Exit 48 BUSINESS Lyman Mountain View Bridger Valley The name "Mountain View" is used for two separate communities in the state of Wyoming. One is just south of this exit on, and the other is a "suburb" of Casper along BUSINESS.
Exit 53 EAST Church Butte Road The reassurance signs in both directions here also have a marker attached. That is wrong, as left (or will join) the freeway at Exit 66 (or hasn't yet joined the freeway). This signage was still in place as of 8/11/97. Dan Stober was in this area around the same time as I and did not notice the shield. That may have been since he was more bothered by the 19-mile construction zone in that area, and the fact that there was no way he was going to get around the long string of trucks and campers in front of him.
Milepost 56 Welcome to Sweetwater County!
Milepost 60 Parking Area
Exit 61 TO Cedar Mountain Road Granger TO WEST Kemmerer
Exit 66 WEST Kemmerer Pocatello, Idaho Fossil Butte National Monument This interchange was expanded in 1996 to allow full access. Previously, eastbound traffic could not take west, and eastbound traffic could not take westbound. This problem is now remedied.
There is a Yellowstone - Grand Teton National Parks via sign here, but it is an indirect route for westbound travelers, unless they plan to see Fossil Butte National Monument first.
EAST
Exit 68 EAST Little America You will see billboards advertising "Little America" for miles on either side of this little Interstate outpost. This is not really a town; it is really a motel, gas station, truck stop, and restaurant all rolled into one. The population of Little America consists of the service center's employees who don't wish to commute from nearby Green River. Other "Little Amnerica" facilities are in Salt Lake City and Cheyenne.
And yes, I admit that does not really get signed for the few miles between Exits 66 and 68. But it is rather fun to include it as one of the routes here, since the two disjointed sections of cannot be otherwise connected without a four-by-four.

By now you've probably guessed that between Exit 68 and Green River is Historic.
Exit 89 BUSINESS TO SOUTH West Flaming Gorge Way Green River Home of the Green River Ordinance. You will see signs indicating enforcement of this ordinance as you enter the city along Business Loop. The Ordinance states that commercial solicitors MUST be registered with the city and have to operate under strict ordinance limits. This law restricts traveling con men from setting up shop and swindling the unsuspecting locals.
Exit 91 BUSINESS TO SOUTH East Flaming Gorge Way Green River Flaming Gorge National Recreation Area via Exits 89 and 91. Expedition Island National Historic Landmark via Business Loop at either Exit 89 or Exit 91.
Historicbetween Exits 91 and 99 has been completely torn up and supplanted by . The only way between Rock Springs and Green River is via the Interstate.
Exit 99 SOUTH East Flaming Gorge Road Vernal, Utah Flaming Gorge National Recreation Area Dinosaur National Monument Via.
EAST NORTH
Exit 102 BUSINESS TO SOUTH Dewar Drive Rock Springs West Look at all of the hotels, fast food joints, and shopping that surrounds this exit. I used to work at one of them -- the Inn at Rock Springs -- as a front desk clerk.
Foothill Blvd, which parallels, is historic between exits 99 and 102. At Milepost 101, notice how Foothill Blvd was realigned to accomodate a planned future interchange to connect with Foothill Blvd on the north and Sunset Drive on the south.
Exit 103 College Drive Western Wyoming Community College LOCAL ACCESS ONLY. This is a rather new interchange completed in 1991.

Exit 146 Sweetwater County Route 24 Patrick Draw Road

Exit 152 Sweetwater County Route 21 Bar X Road
Exit 154 BLM Road Does everyone know what BLM stands for? Well, BLM stands for the Bureau of Land Management, which owns a significant portion of the land not already owned by the U.S. National Park System or by the U.S. Forest Service. I once read that the federal government owns some 70% of the land in Wyoming -- much of that land is the unarable land in the western two-thirds of the state. Ranching outfits typically lease the land from the government for the purposes of grazing livestock. The sometimes conflicting interests between ranchers and the federal governement has ignited what is known as the "Sagebrush Rebellion." It began in Nevada, but the rebellion has since spread throughout the West. Many of the rugged individualists who populate this land disapprove of Washington's interference. Stay tuned for more developments here.

Exit 196 Riner Road As you head eastbound on, note the reassurance sign assembly here. It read, from 1990 to 1994, "EAST, WEST, NORTH." Of course, you're heading east on, not west! As of 8/4/97, the highway department has not fixed that yet.

Exit 246 Halleck Ridge Summit This exit may have been removed during recent reconstruction work and lane expansion. Harold Johnson writes in August 2000, "Wyoming Interstate 80 at Exit 246 (Halleck Ridge Summit) - there is no such exit. (I) was out there yesterday afternoon, with the exit list, and there wasn't any Exit 246 going eastbound, or looking westbound. It does not exist!"

Milepost 371 Port of Entry and Weigh/Check Station. I previously had the westbound Port of Entry at milepost 372. Harold Johnson writes, "Wyoming Interstate 80 westbound Port of Entry is listed in Mile Zone 372. Since the Mile Posts begins from the Utah State Line and increase to Pine Bluffs, ending at 402.78 on the Nebraska State Line, and the Westbound Port of Entry is actually in Mile Zone 371, west of Mile Post 372, that, in fact, puts it in Mile Zone 371, not 372."
Exit 377 SOUTH Hillsdale Between Archer and Pine Bluffs via Durham, Burns, and Egbert (Exits 370 through 391), Historic more closely follows the Union Pacific Railroad via several county roads (Durham Road, Burns Road, and Pine Bluffs Road). This routing is commonly called the "Old Highway" in Southeastern Wyoming.
