It’s the biggest public-works project in Columbus history, and you won’t have to navigate a maze of orange barrels to get around it.
City officials say they’ve changed construction plans for the upcoming installation of a 5.4-mile-long, 18-foot-wide sewer tunnel that’s part of their strategy for eliminating spills into the Scioto River.
Instead of digging deep trenches from the surface to lay the pipe, they’ll burrow 150 feet underground and bore their way from the Arena District to the Jackson Pike Wastewater Treatment Plant on the South Side.
The new method will cut years and dollars off construction time: It will be completed in 2015 instead of 2025 and will cost $231 million instead of the original estimate of up to $388 million.
