Officials say a stretch of Interstate 15 crossing southern Nevada has become the first route in the U.S. West to be designated as an electric vehicle corridor with charging stations available at least every 50 miles.

Nevada Gov. Steve Sisolak marked the milestone at a Jan. 29 ceremony at a truck stop charging station in Mesquite, near the Arizona state line.

A similar facility opened in November in Jean, at the California state line. Sisolak says electrifying Nevada's highways paves the way for what he calls transportation decarbonization.
