Northern Tier to Lewis & Clark?

[KF8MO]

I've heard a suggestion that the Lewis & Clark route east from the mountains to Circle, MT might be nicer riding than the Northern Tier over that stretch. If I wanted to do that, which would be better: jumping off the Northern Tier at Browning, following 89 down to Great Falls, and rejoining the Northern Tier at Circle, or at Chester and taking 223 down to Ft. Benton and on to Circle? Differences in roads, scenery, interesting points along the way, towns/services? Thanks! -Lee

You can go here and click on Bicycle Map to see highway information with traffic counts, shoulder widths, etc. That should help make your decision. US 89 is closer the the Rocky Mountain Front so the views are good. The roads farther east are out on the plains.
