Emergency Closure of 14th Street NW Due to Sewer Tunnel Risk

Northbound lanes of 14th Street NW in Washington, D.C., are closed between L Street and Thomas Circle due to concerns over an abandoned sewer tunnel that is over a century old and at risk of collapse. The closure began early Saturday, February 7, 2026, as a precautionary measure after engineers discovered a significant crack in the tunnel during an inspection prompted by an unrelated water main break.

D.C. Water officials reported that the abandoned sewer tunnel, which is 42 inches wide, was not properly sealed with concrete when it was decommissioned 50 years ago. Sherri Lewis, a spokesperson for D.C. Water, stated, “We did an inspection of this sewer tunnel and found a 70-foot linear crack in the crown of the tunnel.” The stabilization plan involves filling the tunnel with engineered material to support the roadway above and mitigate further risks. This process requires specialized crews and equipment, and it is expected to take several days, with hopes to reopen the road by midweek, weather permitting.

Due to the closure, northbound drivers are being directed to use 13th or 15th streets as alternate routes. Southbound lanes on 14th Street remain open, and pedestrian access is being maintained where safe. Detour signage has been posted to guide commuters, and officials urge travelers to allow extra time for their journeys.

D.C. Water emphasized the urgency of the situation, stating, “The street was initially closed out of an abundance of caution due to the instability of the roadway under the weight of vehicular traffic.” The agency is also coordinating with utility partners to identify nearby utility lines to minimize service disruptions during the repair process.

While the immediate response has focused on public safety, some residents have expressed frustration over the potential length of the closure and its impact on traffic flow in the area. The lack of prior sealing of the tunnel has raised questions about maintenance practices and oversight in the management of aging infrastructure.

D.C. Water plans to begin stabilization work as soon as weather conditions allow, with the goal of completing repairs and reopening the roadway by the end of the week. Continuous updates will be provided to the public regarding the progress of the repairs and any changes to traffic conditions.
