Have you tried looking on the ACA Great Divide maps?
The only time I've been close to there was last summer when we rode the Northern Tier (more or less). We rode north from Libby, MT along beautiful Lake Koocanusa to Eureka, MT which is about 7 miles from Port of Roosville. We then turned southeast toward Whitefish. Then we headed east to Columbia Falls and Glacier National Park. I vaguely remember passing a sign saying I was crossing the Great Divide Route somewhere around there, but I may have been hallucinating.
Here is a link to the Montana Bicycle and Pedestrian Program:

By clicking on BIKE/PEDESTRIAN INFO at the top of the page, you get a drop down list of links to contacts and a bicycle map. The map provides information about traffic counts and road width,

. The last page of the map has some contact information and there is an additional link to contacts which includes bike shops.
An airport (
http://www.glacierairport.com/) is located about 8 miles north of Kalispell. Follow Hwy 2 East and turn into the Glacier Park International Airport. HWY 2 is red on the map, meaning the shoulder is a rumble strip (not bike friendly). Consider a shuttle or taxi into town:
Kalispell Taxi 406.752.4022
Airport Shuttle Service 406.752.2842
Flathead-Glacier Trans. Co. 406.892.3390
Wild Horse Limousine 406.756.2290
On the other hand, there are Amtrak stations in Columbia Falls and Libby.
The employees at Glacier Cyclery, 336 2nd Street, Whitefish, MT 59937
gcyclery@aboutmontana.com were very helpful in giving us some route information for getting to Columbia Falls. It’s a nice shop, too.
