(Prince William County)- The Prince William Board of Supervisors is considering entering into an agreement with a developer to build an athletics facility that would feature an indoor pool, a hydraulic running track and hard-surface courts for basketball, volleyball and pickleball. The facility is proposed along the Interstate 95 corridor in eastern Prince William. Prince William Parks and Rec says the county is considering a number of potential sites for the complex. It could be the largest of its kind in Northern Virginia.
