The 9th Street Tunnel in downtown D.C. remained closed into the evening after a Metrobus fire. Officials say the structure is intact, but ceiling tiles, lighting, and repairs will take time.
A Metrobus fire Thursday evening left a section of downtown Washington’s 9th Street Tunnel closed into the Friday rush, with officials saying the structure is secure but repairs are still needed.
The incident sent heavy, dark smoke into the area near the C St.. SW overpass, prompting concerns for drivers and nearby commuters.. By Friday, D.C.. transportation officials reported that the tunnel did not suffer structural damage, even though intense heat caused significant interior damage.. As of about 5:30 p.m.. the tunnel was still closed. despite earlier expectations that partial reopening could begin during peak afternoon travel.
Officials from the D.C.. Department of Transportation said the tunnel’s steel beams remained secure.. However, the heat was enough to bring down ceiling and wall tiles.. “Overnight, we cleared all of the debris,” said D.C.. transportation director Sharon Kershbaum. adding that crews were still working to remove loose tiles and concrete elements to reduce the risk of falling materials once vehicles return through the corridor.
The plan was for two lanes to reopen at 5 p.m., according to DDOT, but that schedule did not hold.. By 5:34 p.m., all lanes were still closed.. That kind of delay is common in roadway recovery after tunnel incidents. where damage assessment can reveal additional problems that are not visible right away—especially when a fire affects not just the pavement. but also lighting systems and surrounding infrastructure.
For drivers. the operational reality was immediate: the tunnel’s closure changed routes during a critical commute window. forcing detours and congestion spillover onto nearby streets.. DDOT also warned drivers to stay alert. with a particular concern that loose materials could remain until inspections and removal are completed.
After the tunnel partially reopens, at least one lane would still be restricted.. DDOT said the right lane would remain closed for lighting repairs until further notice.. Officials described extensive lighting damage near the fire scene. requiring installation work to restore electrical components and lighting around the affected area.. Temporary striping was reportedly applied where the concrete or asphalt underneath was damaged.
While Friday’s reopening would allow some traffic to move through the tunnel sooner. the cleanup and reconstruction effort is not over.. Kershbaum said crews would continue work over time to restore damaged tile surfaces, lighting, and cameras.. The repairs were characterized as not “urgent” in the sense that the tunnel structure remains safe. but it still represents a meaningful lift for crews coordinating safety checks. electrical work. and restoration inside a confined roadway.
The fire began at roughly 7 p.m.. Thursday, when a hybrid diesel Metrobus caught fire in the tunnel, according to Metro.. The driver was not injured and no other riders were on board when flames started.. Metro officials also said they ordered all 32 hybrid diesel buses from the fleet out of service for inspection following the incident. a step that reflects how transit agencies often respond when equipment in operation is involved in a serious fire.
There’s also a broader lesson in how tunnel disruptions ripple through a city.. When a major corridor closes—even partially—commuters adjust in real time, and traffic patterns shift quickly across surface streets.. That can increase travel times for people who rely on downtown routes for work. school. and evening activities. while also creating additional pressure on law enforcement and transportation crews managing detours.
For now. the key question for Friday is timing: officials are working toward a phased reopening. but damage to the ceiling. lighting. and roadway surface means the tunnel’s return to full normal operations will likely take longer.. Commuters are being advised to watch for updates as crews continue clearing debris. stabilizing loose materials. and restoring systems that keep tunnels safe for day-to-day travel.
