BRATENAHL -- It's the biggest construction project in Northeast Ohio that most of will never see.
The NorthEast Ohio Regional Sewer District conducted a tour of its massive Euclid Creek Tunnel Project.
It's building a three-mile tunnel that will be capable of holding up to 60 million gallons of sewer overflow that now occurs after heavy rainstorms.
For now, that overflow is discharged into Lake Erie, contributing to polluted and unsightly beaches and water.
Under a court-supervised agreement with the EPA, the authority agreed to a $3 billion capital improvements project that raises customers' rates through 2035.
The first tunnel is 3- miles long and 200 feet underground.
It will run from Bratenahl to East 185th Street.
Work on this $200,000,000 project will be completed in 2015.
The second biggest tunnel-making machine in the world is part of the operation.
It had to be lowered piece-by-piece and assembled underground.
This is the first of seven similar massive tunnels.
The water will be treated at the Easterly treatment plant.
The concrete linings for the tunnel are being manufactured in Macedonia.
