Location: Thompson River Rd and US-2, Flathead Cty
Reassurance shield as S-556 begins. 556 is unpaved for its entire length, but fairly scenic.
AMP: 37
Location: Thompson River Rd and Plum Creek Rd, Flathead Cty
This is really kind of an odd highway, in that it’s mostly been bypassed by a private road maintained by Plum Creek, that allows public access. With the exception of this small segment about seven miles south of US-2, they’ll run on separate, parallel rights of way.
AMP: 35
Location: Plum Creek Rd and Thompson River Rd, Sanders Cty
Keep right here to continue on S-556, as we leave the private Plum Creek Rd and join the Sanders County road.
AMP: 32
Location: Thompson River Rd and Plum Creek Rd, Sanders Cty
The county road mostly very closely parallels Plum Creek’s privately maintained but publicly accessible road, leaving this road to a state of more disrepair.
AMP: 28
Location: Thompson River Rd and Plum Creek Rd, Sanders Cty
A couple miles later, we’ll cross the Plum Creek road.
AMP: 4
Location: Thompson River Rd and Forest Rd, Sanders Cty
Several miles later, pavement begins on the county/state road. At this point, Plum Creek’s road is on the other side of the Thompson River.
AMP: 0
Location: Thompson River Rd and MT-200, Sanders Cty
Shortly after that, we’ll approach MT-200, which has no signs due to construction. Follow 200 west to Thompson Falls and 200 east to Plains.
