Waller Creek Tunnel Excavation Over Halfway Complete
It was a full house this morning for an Urban Land Institute breakfast on Waller Creek.
The design competition for the above ground portion of Waller Creek – including an inlet at Waterloo Park, an outlet at Lady Bird Lake, and the creek itself – is nearly at an end. But below ground, there’s still plenty to do.
Joe Pantalion, Deputy Director of the Watershed Protection Department says the Waller Creek tunnel is 60 percent excavated. Once completed, it will keep the water in Waller Creek at a steady flow, and pull 28 acres out of the floodplain.
"It’s actually right on schedule," Pantalion says. "They’ve excavated 2,000 feet north of Fourth Street," the construction site that serves as entrance to the tunnel. "The tunnel’s right under Ninth Street right now. And heading south, the tunnel’s gone about 1,200 feet, which would put it right under the Cesar Chavez bridge [over Waller Creek, between the Austin Convention Center and Iron Works BBQ]."
While the tunnel is nearing completion, Pantalion says most of next year will be spent reinforcing the structure by lining it with concrete. “We hope to have the tunnel, all the pieces connected – the inlet, the tunnel, the outlet – all by the end of 2014,” he says.
In May, KUT News freelancer Jeff Heimsath shot these photos of the tunnel and its construction site near Interstate 35.
