What this tracks
This dataset records the locations and dimensions of tunnels on Tennessee’s interstate highways, state routes, and major local roads.
Why it matters to you
If you’re planning a route for an oversized vehicle, RV, or commercial truck, this data tells you exactly where tunnels are located and how wide they are, helping you avoid getting stuck or causing damage. For emergency responders and logistics companies operating in Tennessee, knowing tunnel locations on routes like SR131 helps with route planning and response times. The width measurements, like the 13.6-foot tunnel recorded on SR131, are critical for determining whether your vehicle can safely pass through.
How to read this data
ROUTE — identifies which highway the tunnel is on, such as SR131 for State Route 131. COUNTY_NAME — shows which county contains the tunnel, like Knox County. WIDTH — measures the tunnel width in feet, with values like 13.6 feet indicating clearance for vehicles. BEG_LOG and END_LOG — mark the exact mile markers where the tunnel starts and ends along the route, such as from mile 6.118 to mile 6.127.
Try it yourself
Look up your regular driving routes to see if any tunnels might affect your travel plans, especially if you drive larger vehicles or are planning to rent a moving truck or RV for an upcoming trip.
