What this tracks
This dataset records specialty pavement markings like stop bars and lane indicators on Tennessee interstates, state routes, and select locally maintained roads.
Why it matters to you
If you’re planning a truck route through Tennessee, this data shows where critical road markings like stop bars exist—helping you anticipate sudden stops or lane merges. For residents, it reveals whether high-traffic exits (like I-75’s Exit 129) have clear lane guidance markings, which could affect your morning commute timing. Businesses near ramps can check if delivery routes have adequate pavement markings for truck navigation.
