To direct the Secretary of Transportation to designate natural gas fueling corridors in the United States for long haul truck traffic, and for other purposes.

Directs the Secretary of Transportation (DOT) to designate natural gas fueling corridors in the United States for long haul truck traffic.

Requires the Secretary, in designating these corridors, to: (1) seek to establish an interconnection of natural gas fueling stations across the United States that will serve the highest possible volume of long haul truck traffic; (2) take into consideration the location of existing natural gas fueling stations, with the goal of having them located no more than 200 miles apart in such corridors; and (3) provide public notice and an opportunity for comment.
