LISTEN: NPS Spokesperson Explained Why A Sinkhole Is Closing Down The Northbound Lanes On GW Memorial Parkway

INTERVIEW — AARON LAROCCA – Chief of Staff of the George Washington Memorial Parkway, National Park Service.

  • Sinkhole Repairs Shut Down Stretch of Northbound George Washington Parkway. Rain has delayed repairs, but the National Park Service hopes to open one lane in time for the Monday evening rush hour. (NBC Washington) — A stretch of northbound George Washington Memorial Parkway will remain closed at least through the Monday morning rush after a sinkhole opened up on Friday. Both northbound lanes between Virginia Route 123/Chain Bridge Road and I-495/Capital Beltway are closed for repairs, the National Park Service said Sunday. Southbound lanes are not affected. Steady rain on Saturday and Sunday prevented the NPS from making repairs, but the agency hopes to open one lane in time for the Monday evening rush hour. Getting that lane open is weather-dependent, NPS says. A preliminary investigation showed that the sinkhole was caused by a 60-year-old, 40-foot deep brick inlet that failed, NPS says. Heavy rain also likely played a factor. The sinkhole is 10 feet deep, 30 feet long and 20 feet wide, NPS says.
