Routing

Interstate 180 is a short divided highway that spurs from Interstate 80 north into downtown Cheyenne. No part of Interstate 180 is freeway, making it a unique Interstate highway. For more on this non-Interstate-standard Interstate, go to Interstate 180 Wyoming.

The Only "Non-Interstate Standard Interstate"

Interstate 180 is unique in that it is not freeway grade or "Interstate standard" at all for its entire length. It has no interchanges except the diamond interchange at Interstate 80. As you drive north from Interstate 80, you hit four at-grade stoplights that are "exits" from Interstate 180.

Exit Number Route Number or Name and Destination Description
Exits 0A-B Interstate 80
EAST Omaha
WEST Laramie
The Interstate 80 junction with Interstate 180 is simply a diamond interchange with stoplights at the base. There is no "freeway-to-freeway connection" normally associated with an dual Interstate highway junction.
Exit 0C Fifth Street (Campstool Road) This "exit" is the third stoplight heading northbound. Between the Fifth and Ninth Street stoplights there is a pedestrian overcrossing.
Exit 0D Ninth Street The fourth stoplight is at the southern base of the Union-Pacific viaduct.
Exit 1 Business Loop I-80/U.S. 30
Lincolnway (Sixteenth Street)
EAST: Pine Bluffs
WEST: Laramie
Interstate 180 ends at this fifth and final stoplight. There are no signs that indicate its northern end. Reassurance signs north of Lincolnway along Central Avenue only indicate Business Loop I-25, U.S. 85, and Business U.S. 87.

Southern Terminus - Interstate 80 - Cheyenne, Wyoming
Perspective from Eastbound Interstate 80
This is the beginning of Interstate 180 from eastbound Interstate 80. Photo taken by Dale Sanderson (4/01).
Base of ramp from eastbound Interstate 80 to northbound Interstate 180. Yes, it is indeed a diamond interchange with traffic lights. Photo taken in August 1998 by Andy Field.
At the end of that offramp, you're greeted with the first of five traffic signals along the length of this Interstate highway. No mention is made of Business Loop I-25 and Business U.S. 87, which run concurrently with Interstate 180 for its entire length. Photo taken by Dale Sanderson (4/01).
Perspective from Westbound Interstate 80
This is the signage for the south beginning of Interstate 180 from westbound Interstate 80. The "bubble shield" for 3dis has appeared in Wyoming, as this is a new sign since 1998. In addition, the fonts vary on these advance signs for Interstate 180/U.S. 85. Compare the extra-wide font here to that on the next sign, below. Photo taken by Dale Sanderson (4/01).
Westbound Interstate 80 approaching Cheyenne exits. The "Central Avenue" exit is for Interstate 180. You can see a refinery in the background. Photo taken in August 1999 by Andy Field.
Perspective from Southbound Interstate 180/U.S. 85/Business Loop I-25/Business U.S. 87
This is looking south on Interstate 180/U.S. 85. The Interstate 180 designation ends at this diamond Interstate 80 interchange, but southbound U.S. 85 (and Business Loop I-25 and Business U.S. 87) continue south, with U.S. 85 reaching Greeley, Colorado. There is not much on U.S. 85 between Greeley and Cheyenne. Photo taken by Dale Sanderson (4/01).
Perspective from Northbound Interstate 180/U.S. 85/Business Loop I-25/Business U.S. 87
Turning left, this is the view. The second stoplight is on the opposite side of the I-80 overpass. Note that the onramp to westbound Interstate 80 is also signed "U.S. 30," which actually runs along Lincolnway, downtown (although this is up to debate - see U.S. 30 Wyoming for more information on this). Note also the Capitol building (under the green light) and the four-shield assembly (the arrow to Laramie points toward it): both are visible in the next photo. You can see almost the entire Interstate 180 route, as its northern terminus is at the northern end of the railroad bridge in the distance. Photo taken by Dale Sanderson (4/01).
The third stop light is at 5th Street (which is at the bottom of the hill, visible behind the "Speed Limit 40" sign). The fourth stop light is at 9th Street; it is obscured by the pedestrian overpass. This photo also shows how the two directions split to go around opposite sides of the U.P.R.R. control tower. Northbound traffic flies over the railyards and aligns with Warren Avenue downtown. The north end of Interstate 180 is at its fifth stoplight (at Lincolnway/Business Loop I-80 and U.S. 30), shown below. Photo taken by Dale Sanderson (4/01).
Northern Terminus - Business Loop I-80/U.S. 30 - downtown Cheyenne, Wyoming
Perspective from Northbound Interstate 180/U.S. 85/Business Loop I-25/Business U.S. 87
This is the north end of Interstate 180. Warren and northbound U.S. 85 are straight ahead; the cross street is Lincolnway. Note in this photo (and those following) the use of the U.S. 87 shield, which actually runs with Interstate 25 along the west side of the city. Photo taken by Dale Sanderson (4/01).
Perspective from Southbound Interstate 180/U.S. 85/Business Loop I-25/Business U.S. 87
This is looking south on Central Avenue/U.S. 85 at Lincolnway. The north beginning of Interstate 180 is straight ahead. You can also see the northbound Interstate 180 viaduct at left. Photo taken by Dale Sanderson (4/01).
Perspective from Eastbound U.S. 30/Business Loop I-80
And finally, this is the north beginning of Interstate 180 as seen from eastbound U.S. 30/Lincolnway. The other viaduct and the four shields are also visible here. Photo taken by Dale Sanderson (4/01).
Perspective from Westbound U.S. 30/Business Loop I-80
Westbound Business Loop I-80 and U.S. 30 at Junction Interstate 180 (and Business Loop I-25, U.S. 85, and Business U.S. 87). Photo taken in August 1998 by Andy Field.
This is looking at the north end of Interstate 180 from westbound Business Loop I-80/U.S. 30 (Lincolnway) at Warren. Southbound Interstate 180 begins to the left one block ahead. Photo taken by Dale Sanderson (4/01).
