CONNECTICUT AVE LANE CLOSURES FOR A/C REPAIRS TO DUPONT, FARRAGUT NORTH METRO STATIONS

Beginning Nov. 5 and lasting through late March, crews will intermittently close lanes on Connecticut Avenue NW to repair the air conditioners at Dupont Circle and Farragut North Metro Stations.

The three-phase operation begins with two weeks of occasional lane closures on Connecticut Avenue NW between Desales and L Streets NW, from 9:30 a.m. through 3:30 p.m.

The second phase of the construction will feature crews working around-the-clock underneath Connecticut Avenue to prepare for the installation of new pipes. In the third phase, workers will work during overnight hours only to install new pipes underneath the roadway.

On Saturday, Nov. 10, Metro will use a crane to lift pipes to the rooftop cooling tower in the 1100 block of Connecticut Avenue, which will result in the temporary closure of the bike lane on L Street.

All of Metro’s underground stations are cooled by systems that move cold water to air handling units. As the water passes through the air handling cooling coils, chilled air is produced for the stations.

The original pipes under Connecticut Ave NW were damaged or have deteriorated to a point where they are no longer functional. Less intrusive efforts to address the situation have all proven unsuccessful and, for the past two summers, Metro has placed a large temporarily cooling tower on Connecticut Ave NW to prevent the stations from becoming dangerously hot. The temporary cooling tower will no longer be needed once permanent repairs are completed.

Metro and DDOT seek to restore chilled air service at the Dupont Circle and Farragut North stations for the start of the cooling season in May.
