Do the corridor pages count Tesla Superchargers?

Yes. Gaps count every public DC fast charging location in our data, Tesla Superchargers included. Each listing shows its network and plugs, so you can see which ones work with your car.

How far from the highway can a listed charger be?

Up to 2 miles in a straight line from CDOT’s line for the highway, and no more than half a mile past either end of the corridor. Distances between chargers are measured along the highway.

How often are the corridor pages updated?

The pages read our live station data whenever they are built; the U.S. Department of Energy’s station list is synced daily 14:00 utc. The downloadable corridor files are rebuilt once a day (daily 07:30 utc), and each keeps the date its rows last changed.

Can I download the corridor data?

Yes. Every corridor has a CSV and a JSON file, free to reuse with credit, listed on this page and on our open data page. Agencies can ask for a weekly file or send corrections.

How are the corridors built?

Each corridor follows CDOT’s highway lines between two named points, and lists every public DC fast charging location in our live station data within 2 miles of it. Gaps are measured along the highway. NEVI compliance comes from our daily test of every designated Colorado highway. The full method.
