FRISCO — Emergency services are responding to a gas leak in Frisco, according to officials.

Representatives with Summit Fire and EMS and Xcel Energy are working to clamp off a gas leak just off Main Street in Frisco, according to Summit Fire spokesman Steve Lipsher.

Lipsher said the leak was caused by construction contractors who accidentally punctured a four-inch gas transmission line with an excavator near Third Avenue and Granite Street.

Evacuations are in place at buildings on the south side of Main Street between Third and Fourth avenues, including Bagalis, Rainbow Court, Hotel Frisco and The Uptown on Main. Lipsher said the alleyway behind the buildings also has been closed.

Lipsher said crews with Xcel are on scene to fix the issue but will have to dig a large hole to be able to clamp the line, which could take some time.

“Main Street is still open,” Lipsher said. “We’re just there to monitor it and make sure we don’t have any subsequent problems. People will smell natural gas on that side of Frisco until the wind blows it away, and it vents properly. But it’s not a concern from outside the evacuation zone.”
