This state's highway naming convention is up for debate above. Feel free to participate. --Rschen7754 (talk - contribs) 05:46, 4 September 2006 (UTC)Reply

Other numbers

Maps such as [1] show an additional layer of numbering (N- and P- numbers) that often agree with the state highway numbers. They may be related to the functional classification.

The functional classification designations refer to the various funding pots available for maintenance funding. "I" is used exclusively for federal Interstates. "N" is used for all other National Highway System-funded routes, even those completely signed as state highways. "P" routes are generally Primary State Highway System, "S" routes are Secondary State Highway System, and "U" routes are Urban routes through city and urban limits. Older editions of the road log also listed "X" for off-system routes eligible for other funding, e.g. MT 38 is X-81024, even though it has a Primary route number, because most of its route is through National Forest land. (MT 49 is also affected this way.) Off-system routes are still listed in the state GIS database. 184.166.187.64 (talk) 10:35, 4 May 2017 (UTC)Reply

Missing primary state route info

Latest comment: 7 years ago2 comments2 people in discussion

Just an FYI, I can't find any trace of MT-10 or MT-89 on Google Maps or other sources. Perhaps they're decommissioned routes? Someone who's native to Montana and/or knows how to read the MT route logs may be able to figure this out.71.58.106.195 (talk) 05:30, 4 March 2017 (UTC)Reply

I have been doing extensive research on the historical Montana state highway maps dating back to 1935, and based on this research, it appears MT 10 and MT 89 have never been assigned. Very rarely has Montana used state route numbers when an active federal route with the same number exists. The only historical exceptions are MT 287 (established before the US 287 designation replacing most of MT 287), 1935-era MT 191 (replaced by US 287) from US 191 to near Three Forks, MT 87 (nowhere near the US route), and MT 2 (replaced a section of old US 10 from Butte to Three Forks, but nowhere near the US route). 184.166.187.64 (talk) 10:06, 4 May 2017 (UTC)Reply
