Interstate 90, US-12 to MT-88

 

AMP: 174

Location: I-90 and US Highway 10, Powell Cty

In a mile, exit for a connector back up to US 12. The route in question used to be US 10, and is designated as such in Powell County, but it’s not actually that. I’m not really sure what the route designation is, but the internal designation is 88, so I’ll roll with that a la Montana 68 in Cascade.  You could also call it US 12 Spur, I guess, or just say it’s an unnumbered state highway.
