What this tracks
This dataset measures how bicycle-friendly major roads are throughout Tennessee, rating each road segment with letter grades from A to F.
Why it matters to you
If you’re planning a bike commute or recreational ride in Tennessee, this data tells you which roads are safest and most comfortable for cycling before you head out. A road with an “A” rating likely has bike lanes and lower traffic, while an “F” rating means heavy traffic with no bike infrastructure. Business owners near highly-rated bike routes can better understand their potential cycling customer base and plan bike-friendly amenities accordingly.
