U.S. highways have 878 stretches of 50+ miles with no fast EV charger (map)

A regularly updated inventory maps U.S. highway stretches where public DC fast chargers are more than 50 miles apart, using a daily check of open chargers across the 50 states and Washington, DC. The November 10, 2026 snapshot identifies 878 such gaps in 42 states, spanning 73,239 miles of highway. Most are 50-100 miles long (697); 168 are 100-200 miles, and 13 exceed 200 miles. The largest is a 376.6-mile stretch of US-2 in Montana, from the Idaho state line to Tilleman Motors. Texas has the most gaps - 98, covering 8,581 miles.

The figures show that the issue extends beyond remote U.S. routes: 126 gaps are on Interstates, with the longest, 168.9 miles, on I-29 in South Dakota. Another 309 gaps overlap federally designated EV Alternative Fuel Corridors, accounting for 21,083 miles of road. The inventory also evaluates 15,940 open public fast-charging stations against three federal NEVI minimum requirements; 2,556 meet all three. A map and sortable table provide each gap’s route, length, and endpoints, with CSV and JSON downloads for further analysis. The data can help travelers identify charging breaks and planners see where coverage remains sparse.
