This was the largest state on the trip and it took me the longest time to get through it (12 days).
The Montana Frontage Road runs across the state along I-90 west of Billings and I-94 east of it. It is well paved with light traffic for the most part. Even without shoulders, it is a good option for coast-to-coast rides. But it can be discontinued for various reasons (private properties, geography, etc.) and other road options, including interstate highways, must be considered.
There were roadside memorials of the same types of crosses in MT. They could be a single cross, or several together. The most I saw was five. Sometimes, they were separated by small distances. I guess they belonged to different families or groups perished in the same accidents. I saw such roadside memorials more on the local roads than interstate highways. No other state has such consistent roadside memorials throughout the entire state.
