At Least Five Northeast Ohio Communities Pause Directional Drilling After Twinsburg Township Gas Explosion

A horizontal directional drilling (HDD) crew installing fiber-optic internet struck a natural gas line in a Twinsburg Township, Ohio neighborhood on Thursday, June 25, 2026, triggering an explosion that destroyed three homes and damaged dozens more. Within two days, at least five Northeast Ohio communities halted directional drilling in their rights-of-way while the cause is investigated. For the underground utility sector, the incident is a textbook example of the blind-bore failure that non-destructive potholing and vacuum excavation are designed to prevent.

What happened on Hiram Lane

Twinsburg firefighters were dispatched around 3:20 p.m. for a report of a gas smell on Hiram Lane in the Woodlands subdivision of Twinsburg Township, in Summit County. According to Fire Chief Earl Wilson, crews smelled gas, called the utility, and backed off. The blast occurred within about two minutes of Enbridge gas-company crews arriving on scene.

Three homes were destroyed: the home where the initial explosion occurred plus its two neighbors. Damage assessments to surrounding houses climbed as the days passed. Early reporting cited lower figures of roughly 20 to 23 damaged homes, but the settled count rose to at least 36 additional homes damaged. Two neighborhood residents suffered minor injuries and were treated and released; there were no fatalities. The residents of the home where the blast originated were not home at the time.

A shelter-in-place order for Hiram Lane, Hiram Square and Dorset Lane was issued and lifted the same evening. Chief Wilson urged the public to avoid the area over the following days as the investigation began.

The natural gas utility involved is Enbridge Gas Ohio, which said it was working to repair the pipeline and restore service. The leak was caused by a fiber-internet directional drilling subcontractor striking the gas line; the crew was tied to Windstream's Kinetic Fiber Internet brand, whose parent is Uniti Group. Uniti Group attributes the strike to inaccurate underground-utility markings by a third-party locating service, saying its subcontractor struck the line while installing fiber optics. The cause of the ignition remains under investigation by the Ohio State Fire Marshal's Office and the Public Utilities Commission of Ohio (PUCO).

The municipal pauses, community by community

In the days after the blast, at least five Northeast Ohio communities paused directional drilling. A sixth, Streetsboro, was also reported to have suspended work.

Green Mayor Rocco Yeargin said, "It is important to take time to understand what happened and learn from it before work continues." Hudson's action carries added weight because, in the same reporting, Hudson fiber crews had struck gas and water lines multiple times in prior weeks. In Kent, the fire department began hand-delivering suspension notices to fiber companies. Separately, News 5 Cleveland reports that Twinsburg Township, which is distinct from the City of Twinsburg, paused all digging in township rights-of-way under Township Manager Rob Kager.

These are municipal permit actions, not a state moratorium

It is worth being precise about the legal mechanism, because it is easy to misread. Every documented pause is a city- or township-level right-of-way or permit action, not a statewide moratorium. Kent suspended right-of-way permits; Twinsburg Township paused digging in township rights-of-way. The state role here is investigatory only, carried out by PUCO and the Ohio State Fire Marshal.

This matters because Ohio's regulatory landscape is often conflated. ODNR's Division of Oil and Gas Resources Management holds sole and exclusive authority over oil and gas wells and production operations under ORC Chapter 1509. Installing fiber by HDD in a road right-of-way is not a well, and it falls outside that chapter. Utility work in Ohio rights-of-way is instead permitted and regulated by municipalities under ORC Chapter 4939 and by county engineers, while the struck gas distribution main is a PUCO-regulated pipeline.

Layered on top is Ohio's damage-prevention law. The state's one-call system is the Ohio Utilities Protection Service, doing business as OHIO811, a nonprofit clearinghouse rather than a regulator. The underlying duties rest on ORC Chapters 3781 and 4913 and Section 153.64, with PUCO enforcing through the Underground Technical Committee. Excavators must notify 811 at least two working days before digging, and utilities must then locate and mark buried lines within two working days using the standard color code, high-visibility yellow for gas and oil. A locate or marking failure on a gas main is a defined statutory compliance failure, which is exactly what Uniti's initial account describes.

The hydrovac angle: a blind bore is the failure mode potholing prevents

For hydro-excavation professionals, the technical lesson is direct. HDD is a steered blind bore: the drill head advances through unseen soil guided only by a surface tracker, so a strike on a pressurized gas main can cause fire and explosion, while open-cut methods expose the pipe before contact. Crucially, 811 marks carry horizontal tolerance and no reliable depth, so paint on the ground does not, on its own, prove clearance for a bore passing beneath it.

That gap is precisely why OSHA advises exposing buried utilities by vacuum excavation or hand digging, known as daylighting or potholing, before HDD boring, and singles out gas lines as a special explosion and fire hazard. The Common Ground Alliance's Best Practice 5.20 names hand digging, soft digging and vacuum excavation as recognized methods for safely exposing a facility within the tolerance zone, the facility width plus a horizontal buffer, commonly 18 to 24 inches depending on the state. In practice, vacuum-excavation potholing is the standard verification step before an HDD bore or utility crossing, physically exposing the line so the drill can be steered clear. Hudson's new requirement to switch to hydro excavating with a city inspector present before drilling reflects that logic.

The industry data underscores how routine bad locates are. The CGA's 2024 DIRT Report analyzed 196,977 unique damage reports across the U.S. and Canada, with its index worsening from 94.0 to 96.7. Locating and marking failures are the single largest damage-cause bucket, roughly 31 percent of all damages. CGA also notes the same top six root causes have driven about 76 percent of incidents for three straight years, and locate delays mean excavators start on time only about half the time.

What contractors and utilities should take away

The backdrop is a wave of underground fiber construction. The federal $42.45 billion BEAD broadband program is driving large volumes of fiber builds, most via HDD, with major work expected across roughly 2026 to 2030. Industry observers link that surge in blind boring to a corresponding rise in strike risk when locate accuracy lags.

The takeaway is not that HDD is unsafe, but that a paint mark is a starting point, not a clearance. Where a bore crosses or parallels a gas main, daylighting the line with vacuum excavation before drilling converts an unverified assumption into a confirmed position and depth. For utilities and municipalities writing right-of-way permits, requiring potholing at gas crossings, as Hudson now does, is a low-cost control against a high-consequence event. The pauses across Northeast Ohio are temporary and local, but they point at a durable question the trade has already answered: verify before you bore.
