Business Loop I-25 - Casper

Routing

In Casper (Yellowstone Highway and Center Street), Business Loop I-25 follows Wyoming 255 and Business U.S. 20-26. Most maps do not show this route, and it is not exactly easy to find by looking at the Casper metropolitan area map. However, the Wyoming Highway Department has made an effort to let travelers know where it is. Of course, it is signed as its two connections with Interstate 25 (Exits 186 and 188A), but it is also mentioned at the junction of Business U.S. 20-26 and Bypass U.S. 20-26.

After leaving the Yellowstone Highway (Second Street), Business Loop I-25, Business U.S. 87, and Wyoming 255 travel north on Center Street to return to Interstate 25. For a city of such size, it is surprising that the business loop is as short as it is, essentially only serving downtown. Here Center Street intersects B Street. Photo taken 09/01/04.
A grade separation allows for an offramp to the Casper post office, with a connection to C Street. Photo taken 09/01/04.
Center Street passes under the railroad tracks at this grade separation. Photo taken 09/01/04.
Immediately thereafter, the business route intersects with Interstate 25 and U.S. 20-26-87. The first ramp connects directly with eastbound; follow the signs onto the frontage road for westbound/northbound. Photo taken 09/01/04.
The frontage road (West F Street) carries the business loop over the North Platte River. Photo taken 09/01/04.
West F Street is an older bridge with older guardrail. Photo taken 09/01/04.
Finally, the business route rejoins Interstate 25 at the Poplar Street (Wyoming 220) interchange. Photo taken 09/01/04.
