Updated at 2:57pm Communities along the Potomac River shoreline could be in for some noisy nights. Starting at 11pm on Monday, overnight construction work begins at Reagan National Airport to improve the main runway. Construction was supposed to begin tonight, but the contractor has more preliminary work to complete.
Crews will be pile driving from 11pm-6am for about the next three months so there is no interference with flights during the day. More than 200 existing piles will be replaced on a pier just south of the main runway, and the pier will be renovated.
