End of US highway 189 |
 |
1939-present
- North: Jackson, WY
- South: Provo, UT
|
Before today's US 189 was commissioned, there was a different US 189 in Utah.
The south end of modern US 189 has always been in Provo... but before I-15 was built, its terminus was at US 89. Here we are looking east on 300 South, which is also southbound US 89: |

University Avenue is the crossroad; originally US 189 began to the left. But today if a driver turns right and goes about a mile-and-a-half, they will come to the modern south end of US 189, which is at its interchange with I-15:

In the distance is Loafer Mountain. It was not mandatory to take one of those I-15 exits; drivers had the option to continue straight ahead, which took them to the intersection with 1860 South, where a right or left turn was required:

That "End" assembly was added sometime between 2009-2012; straight ahead is the offramp from northbound I-15. Signage for traffic heading that direction formerly looked like this:

Note that is exit 263; UDoT renumbered their interchanges shortly before that photo was taken. The old number is shown in the first of these two photos, which were both taken from southbound I-15:

Part of Spanish Fork Peak is visible in the background. As of 2016 that interchange was being reconfigured, but at the time, drivers exiting to the right would loop around and go over the second bridge. They would then be on 1860 South, and would have to make a left turn to get on US 189 (University). Not far past that intersection, the first northbound confirming marker was posted:

Heading that direction affords spectacular views of Mount Timpanogos. Continuing that way we soon come to the historic south beginning of US 189 at 300 South:

The north end of US 189 has always been in Jackson. Today, 12 miles south of town, at Hoback Junction, US 26-89 joins with US 189-191, and the four routes are overlapped along the single highway heading north into Jackson (Wyoming has no aversion to route concurrencies). But it has not always been that way:

At that time, there was no bridge over the Snake River at Hoback, so US 189 traffic had to go all the way up to Jackson in order to junction with its "parent" route (US 89). That junction is shown here:

Southbound US 89 was to the left, while straight ahead was northbound US 89. But US 189 probably did not end there, just as it does not end there today. This route has an unusual terminus, in that it does not terminate at a junction with another highway. Rather, it continues for another mile, carrying travelers into downtown Jackson, and then ends (while the three other routes continue on):

Although the main highway is ultimately a north/south road that leads to Grand Teton and Yellowstone National Parks, for a short distance through Jackson traffic is routed onto Broadway, which is an east/west street. That photo was taken there; the sign was posted in the block between Millward and Glenwood streets. The intersection after that is Cache Street, onto which highways US 26-89-191 continue (note the assembly in the distance). But US 189 does not make it out of downtown Jackson. The photo below is looking south on Cache:

Snow King Mountain dominates the view in that direction, and one of the ski runs is visible in that photo. US 26-89-191 continues to the right, and US 189 begins that way. If a traveler takes that turn, they will soon see the confirming assembly shown here:

It should be noted that, for about 25 years, US 189 had a signage gap in Utah. Internally, the Utah Dept. of Transportation defines US 189 as being concurrent with US 40 north of Heber City, and ending at the same place US 40 does: at I-80 near Park City. The past several issues of their official state highway maps have indicated this:

c. 2014, UDoT

However, there are a few problems with that. First, UDoT is ignoring the segment of US 189 in Wyoming: travelers must use I-80 to get there. Furthermore, for about 25 years, the signage UDoT actually posted for US 189 did not match its own route definition. US 189 was not signed anywhere between Heber City and Silver Creek Jct; that entire segment was posted only as US 40. And not only that, but there was an "End US 189" assembly posted in Heber from the early 1990s until 2017:

That particular "End" assembly was gone as of July 2010, but another one was added (on the opposite side of the road) in 2012, and it remained until 2017. But here is the assembly that was posted after that time:

Historically, US 189 turned left there for an overlap with US 40 through Heber City, and then split away to route through Kamas and Peoa (essentially along what is now U-32, most of which is visible on the map above). That meets I-80 at Wanship, and from there US 189 was concurrent with it to the Wyoming state line, through Evanston, and then up north to Jackson. But when the Jordanelle Reservoir was constructed (see map above), part of old US 189 had to be rerouted to higher ground. When that happened, it seems that UDoT took the opportunity to reroute US 189 such that it heads north with US 40 to Silver Creek Jct, and they renumbered the segment of old US 189 between Heber and Wanship as U-32. But for some reason, instead of signing US 189 as it had been redefined, UDoT instead posted that junction in Heber as the north end of US 189. Apparently UDoT never obtained AASHTO's approval to do any of this -- and if they would have tried, AASHTO probably would have rejected the request, because UDoT's action resulted in two disconnected segments of US 189 (one in Utah and one in Wyoming).
|
Regardless, that all changed in late 2017: UDoT finally added US 189 trailblazers along the segment of US 40 north of Heber...
|
...and now when northbound travelers reach I-80 at Silver Creek Jct. a sign instructs northbound US 189 traffic to continue via eastbound I-80:

US 189 is not dual-signed along I-80, but that is not uncommon (for example, see Utah's neighbor, Colorado). In contrast, another of Utah's neighbors, Wyoming, does an excellent job posting US routes where they are concurrent with interstates, and US 189 shields appear along I-80 as soon as drivers cross the state line:
