Road Quality and Infrastructure Safety

I-80 in Wyoming is well-maintained but features long, straight stretches with strong crosswinds. I-90 through Montana has excellent pavement and rest areas every 50-70 miles. US-12 from Lolo Pass to Lolo is narrow, winding, and scenic; watch for logging trucks and deer. Shoulder width varies; use turnouts for slower vehicles.

• Rest areas: 11 along I-90 in Montana (e.g., near Big Timber, Livingston).
• Cell coverage: strong on interstates; spotty on US-12 (check offline maps).
• Emergency services: Highway patrol numbers noted at rest stops.
