 Fairfax County is asking for a new federal grant that could help reimagine and improve that stretch of road. Late last month, the County Board of Supervisors applied for a grant that would help come up with a plan to make that stretch of 29 better for pedestrians, cyclists, and drivers. Right now, there's not much in the way of sidewalks or bike lanes along that four-lane stretch. Fairfax now says the county hopes to someday widen it to a six-lane road with room for pedestrians and cyclists, including safe ways to cross the road.
