The Maryland State Highway Administration is closing the Nave’s Crossroads Park and Ride this weekend, to improve the lots. All cars need to be removed from the lots by this evening, to allow crews to begin work tomorrow morning. Weather permitting, the project will be complete by Sunday evening at 6 p.m. Crews will clean drainage ditches, cut trees and brush, paint pavement markings and replace parking curbs. No vehicles will be allowed to enter the lots after 2 p.m. today, and all vehicles must be removed by 10 p.m. Cars that are not removed by 10 p.m. this evening will be towed at the owner’s expense.
