The Fairfax County Department of Transportation (FCDOT) received a $50,591,220  grant from the Federal Transit Administration to buy low-emission diesel-electric hybrid buses. The grant assists Fairfax County in replacing older buses as part of its ongoing fleet replacement plan, which is progressing toward a more environmentally friendly public transportation system and improved service.

“Adding these low emission, diesel-electric hybrid buses to our fleet supports our commitment to our riders and to reducing our carbon footprint," Fairfax County Board of Supervisors Chairman Jeff McKay said.

Fairfax County's project is significant because it was the only one selected within the Commonwealth of Virginia, highlighting the competitiveness of this funding round. The Board of Supervisors authorized the Fairfax County Department of Transportation to apply for this funding on May 7, 2024.
