DALLAS (1080 KRLD) - Flood relief will soon be coming to areas of Dallas, thanks to Big Tex. No, not that Big Tex.

In this case, “Big Tex” is the name of the largest tunnel boring machine ever assembled in the state of Texas.

“It’s 38 feet in diameter by 230 feet long,” says Dallas City Councilman Lee Kleinman.

Once lowered into place, Big Tex will carve out a five-mile underground tunnel that provides drainage relief to areas of east and southeast Dallas.

“Some of these major areas include Baylor Hospital, the area south of Buckner Park, the Fair Park area, the St. Thomas area near Woodall Rodgers Freeway,” says Mayor Pro Tem Adam Medrano.

Disruptions will be kept to a minimum.

“There will be minimal utility relocation, as well as minimal street and traffic impacts,” says Assistant City Manager Majed Al-Ghafry.

The tunnel-boring machine will be lowered into place underground piece by piece starting Wednesday, and the lowering and reassembly process is expected to last two to three months.

As for its name, “Big Tex”? “The name was given by the permission of the State Fair of Texas,” says Councilman Adam Bazaldua.
