In general, DC is a quasi-ghost town over Memorial Day, July 4th, and Labor Day weekends. Most people in the metro area head out to the beaches or at least to somewhere not as swampy and humid. I'd also second the recommendation to avoid I-95 like the plague on that Monday as all the beach and tourist traffic will be on the highway.
