11:28 AM: Thanks to Kay for the tip. SFD is at Highland Park Way/Austin/Holden for a natural-gas leak response; avoid the area.

11:55 AM: Highland Park Way hill is closed because of this. Neighbors remind you to please slow down when detouring through neighborhoods.

12:04 PM: We’ve arrived in the area to try to find out more. Heading eastbound on Holden, it’s closed at 11th. Also, note that Metro Route 131 is rerouted because of the closures.

12:16 PM: SFD tells us a 2″ gas line was punctured by a construction crew. City Light is also in the area because they decided to take down the power as a precaution until the leak can be stopped. Meantime, approaching the area northbound, 9th is blocked at Kenyon.

12:39 PM: SFD has closed out the call and buses have resumed their regular routing, indicating roads have reopened (we’re headed back to check).

12:45 PM: Confirmed – all back open.

4 PM: We asked SDOT if the crew was theirs or a contractor’s, since they’ve been working in the area. Here’s the response from spokesperson Ethan Bergerson:

Workers for KC Equipment punctured a gas line this morning at 10:45 am. KC Equipment is a private construction firm on contract with SDOT to build a new traffic signal at SW Holden St and Highland Park Way SW. KC Equipment immediately reported the incident to Puget Sound Energy.

Puget Sound Energy crews arrived on site and confirmed that they had patched the line and that the area was safe shortly after noon. Seattle Fire Department, Seattle Police Department, and Seattle City Light were all also on-site to assist with ensuring public safety.

He adds that no injuries were reported.
