Frequently Asked Questions
What roads does Signal Mountain Roads track?
We track three roads that connect Signal Mountain to Chattanooga, Tennessee: Signal Mountain Blvd (US-127), "W" Road, and Roberts Mill Road.
What is Signal Mountain Blvd?
Signal Mountain Blvd is the main artery connecting Signal Mountain to Chattanooga. It is also known as US-127, Signal Mountain Road, Ridgeway Ave, and Taft Highway. It is the most heavily traveled of the three roads and is critical for daily commuters.
What is "W" Road?
"W" Road is named for the shape it makes on the mountainside — it is not an abbreviation for any word. It features three hairpin switchbacks near the summit, which are the most common trouble spots during winter weather. Ice and snow accumulate quickly at the switchbacks and conditions there can change faster than the rest of the road.
What is Roberts Mill Road?
Roberts Mill Road is an alternate route up Signal Mountain. It is frequently checked by residents for ice, debris, and weather-related closures, particularly when conditions on the other routes are poor.
How do I check current road conditions on Signal Mountain?
Visit app.signalmountainroads.info to see the latest community-submitted road condition reports. Reports are sorted by date and show which road was reported, when, and what conditions were observed.
How do I submit a road condition report?
Go to app.signalmountainroads.info/report and fill in the road name and a brief description of what you observed. It takes about 10 seconds. No account required.
Are the road conditions real-time?
Yes. Reports appear immediately after submission. The most recent report for each road is shown at the top of the feed. Conditions are only as current as the most recent report — if no one has driven the road recently, the latest report may be older.
What causes road closures or hazards on Signal Mountain?
The most common hazards are ice and snow in winter, particularly on the hairpin switchbacks of "W" Road and shaded sections of Signal Mountain Blvd. Debris, fallen trees, and accidents are also reported year-round.

Yes. Developers and third-party apps can access road condition data at api.signalmountainroads.info/llm (no key required) for the latest report per road, or use the full API at api.signalmountainroads.info with an API key.
