Traffic Advisory: Sinkhole Repairs Will Result in Extended Irving Street Closure

October 20, 2020

A section of Irving Street NW near Rock Creek Park will be closed to all traffic for several weeks to allow DC Water to make urgent repairs to a historic sewer line that collapsed and created a sinkhole. There will also be closure in the 3000 block of 18th Street NW, just north of Irving Street.
 
The sinkhole in the 1800 block of Irving Street did not cause any injuries and neither water nor wastewater service has so far been impacted, but the repairs are complex and will take at least two weeks to complete.
 
DC Water has worked closely with the DC Department of Transportation on the street closing and equipment staging; Irving Street in this section runs one way, eastbound.
 
DC Water is also working closely with WMATA so that Metro bus service can be rerouted around Irving Street.
