More than 3,000 new Park & Ride spaces will be built along the Interstate 95/395 corridor in Fairfax, Prince William, Stafford and Spotsylvania counties and the city of Fredericksburg to accommodate carpoolers, sluggers and transit users, Virginia officials say. These spaces will be completed by the time the northern section of the HOT lanes opens in 2012.According to state officials, an additional 3,750 Park & Ride spaces will be funded through an anticipated concession payment from private partners. The Department of Rail and Public Transportation and local transit operators conducted a study of the I-95/395 corridor and identified the additional Park & Ride spaces as a possible use for the private funding.The location of the Park & Ride improvements will be determined through coordination with local jurisdictions and transit operators. This map shows the location of the proposed lots. The public is invited to comment on the proposed Park & Ride improvements at public hearings this week.The public hearings will be held from 5 to 9 p.m. tomorrow (snow date Feb. 12) at Potomac High School, 3401 Panther Pride Dr., Dumfries; 5 to 9 p.m. Tuesday (snow date Feb. 19) at Robert E.
