Gas leak on U.S. 23 near Northwoods Boulevard disrupts north Columbus traffic and prompts emergency response

Incident triggers partial shutdown and backups on a key commuter corridor

A natural gas leak along U.S. 23 in north Columbus disrupted traffic on Thursday, March 12, 2026, after a gas line was struck near the Northwoods Boulevard area, prompting an emergency response and lane and/or roadway restrictions in the vicinity.

Motorists reported stop-and-go conditions and prolonged delays in both directions on U.S. 23 near Northwoods Boulevard and nearby neighborhood access points. The disruption affected a stretch of roadway that serves as a primary north-south route for commuters traveling between Columbus and communities in southern Delaware County, where recurring congestion is already a well-documented challenge during peak hours.

What is known about the cause and immediate response

Available, independently confirmable information indicates the leak began after construction activity struck a gas line near the roadway. In incidents of this type, first responders typically prioritize securing the area, limiting ignition sources, and establishing a perimeter while utility crews isolate the line and begin repairs.

Officials had not publicly released detailed information within the initial reports about the size of the line, the estimated volume released, or whether any nearby buildings required evacuation. No verified injuries were reported in the initial accounts connected to the traffic alert.

Traffic impacts and what drivers should expect in similar events

Gas leaks on or near major roads frequently require temporary closures because even a localized release can pose risks if gas accumulates or encounters an ignition source. On U.S. 23, any restriction can quickly cascade into significant backups due to limited alternate routes and heavy commuter volumes.

• Drivers approaching the area can expect sudden slowdowns, intermittent stoppages, and detours around restricted ramps or cross streets.
• Congestion may extend well beyond the immediate work zone as traffic compresses at merge points and signalized intersections.
• Reopening timelines generally depend on how quickly utility crews can shut off gas flow, confirm atmospheric readings are safe, and complete initial repairs.

Context: U.S. 23 remains sensitive to disruptions

The corridor north of Columbus has been the focus of ongoing safety and congestion discussions as growth continues along the route. Even routine utility work or minor incidents can produce outsized delays when they occur near major access points such as Northwoods Boulevard and Lazelle Road.

Safety protocols in gas-leak responses typically require traffic control and securing nearby areas until measurements confirm conditions are stable.

What residents can do

Residents who smell natural gas are generally advised to leave the immediate area, avoid operating anything that could spark (including switches and vehicles if they are adjacent to the leak), and contact emergency services or the local gas utility from a safe location. For commuters, checking real-time navigation apps before entering U.S. 23 can reduce the risk of being trapped in a closure-related backup.
