This is one of the big holiday weekends when many travelers leave the D.C. region while many others head into it for Memorial Day activities. The highway departments will suspend road work for the peak travel times, but Metro is shutting stations on the Red and Orange lines.

One exception to the roadwork suspension: Crews continue to work on that sinkhole that opened up at 14th and F streets NW.

The Capital Weather Gang says the cool-down will last through the long weekend, but the days will become increasingly sunny.

The Nationals play the Phillies through Sunday, and have a Memorial Day afternoon game with the Orioles. Those games are likely to draw many out-of-town fans into D.C. At RFK Stadium, D.C. United will play the Portland Timbers at 7 p.m. Saturday.

The Delaplane Strawberry Festival is 10 a.m. to 5 p.m. Saturday and Sunday at Sky Meadows State Park, also a great place for a hike along the Appalachian Trail. See more event listings in the Going Out Guide.

The peak period for the holiday getaway usually is 1 to 8 p.m. Friday. Use this link to our summer getaway guide.

Virginia traffic patterns

The Virginia Department of Transportation took a look at historic traffic data to see the times and places where congestion has been heaviest on Memorial Day weekends. While history doesn’t necessarily foretell the future, it’s useful to see the traditional hotspots statewide:

  • Interstate 95 southbound between Lorton and Fredericksburg on Friday afternoon through Saturday morning.
  • Interstate 95 northbound between Interstate 295 in Richmond and Doswell, and between Thornburg and Dumfries, on Monday afternoon and evening.
  • Interstate 64 eastbound between Interstate 664 and Willoughby Spit on Friday and Saturday afternoons.
  • Interstate 64 westbound between Granby Street and Willoughby Spit on Friday and Monday afternoons.
  • Interstate 81 northbound between Lexington and Fairfield on Monday afternoon.
