Title: MT: BL-15 Helena
Post by: US 89 on June 04, 2022, 07:54:35 pm
It appears TM has a portion of the I-15 business loop through Helena on the wrong roads. TM has the business loop following 11th Ave and Last Chance Gulch between the 11th/Montana and Last Chance/Lyndale intersections, but it looks like the business loop just follows Montana and Lyndale between those two points (in other words, concurrent with US 12).

I was up there a month ago and did not see any sort of BL-15 signage on this downtown portion, but it is apparently signed on Lyndale eastbound just past Last Chance (http://www.corcohighways.org/highways/mt/15helena/12to229/1.jpg).

A little frustrating, as that means I didn't actually complete my intended clinch of that business loop.

So this route has come up before:

OK, usually if there's signage from the interstate that's usually a good reason to keep something in the HB. If no one else has an objection, I'll take the US 12 business loop out in the next few days.

As I mentioned there, the only reason it's still in there at all is because it's signed from I-15. All the signage there is is just "TO" shields, so I'm not sure what the routing actually is. I'm fine with moving it to US 12; since there's no actual signage I can do whatever I want with it lol. Anyone else have any suggestions? Since the signage is so bad, I would drop it from the HB, but it's signed from I-15 at both ends...

So, I'd say leave it as is then. If signage is inconsistent or unclear, defer to what's official on paper.

Heh, sure enough. I was looking for a MDT map like that but couldn't find it.

Yeah, that's what I'm going to do; I found that after I typed up most of my first post but didn't want to delete it lol.
