ARLINGTON, Va. — Metro officials have announced the Pentagon Metro station has reopened after flooding delayed trains Wednesday morning.

Pentagon station was closed and trains were temporarily bypassing the station because of flooding in the station’s mezzanine area.

Arlington DES crews were called to the scene to investigate the incident. Crews discovered the source and learned that it was a break in a private WMATA water line. 

Officials say the water flow has stopped at the station.

The blue and yellow lines were experiencing delays and officials requested the assistance of shuttle bus services.

For commuters taking the blue line, bus services are available between Pentagon City and Arlington Cemetery. And for those taking the yellow line, bus services are available between Pentagon City and L'Enfant Plaza. 

As of 11 a.m., trains were still bypassing the Pentagon station. Metro set up emergency shuttle buses to pick up riders from adjacent stations—Pentagon City and Arlington Cemetery.

Passengers at the station tweeted pictures of the flooding inside of the station. It appears passengers are walking through water to get to their trains.

One rider tweeted that the Metro station required "a boat and some oars."

Metro stations have flooded in the past. In July, a downpour of rain led to a waterfall in the ceiling of Virginia Square Metro. WMATA spokesperson Dan Stessel then that the incident was caused clogged storm drains rushing water into street-level, station ventilation shafts.

WMATA launched an extensive waterproofing pilot project on the Red Line in July 2017, resulting in months of single-tracking and suspended service over weekends.

The nine-mile long project stretched between Farragut North and Grovesnor and included a technique called, "curtain grouting," that added a waterproof, polymer-based layer to the exterior of tunnel walls.
