The State Highway Administration is reminding Washington County residents that a major road project will be starting June 23rd and they should prepare for a significant traffic shift. The project to rehabilitate the US 40 bridge over Conococheague Creek will require a full bridge closure and a 15-month detour to maintain safety. To accommodate the work, traffic will be rerouted onto MD 68, 63 and I-70. The detour is expected to remain in place until August of 2026.
