NEWS: Boring hasn’t been this exciting for a long time as Mackenzie breaks through

At 1:27 a.m. Wednesday, Mackenzie saw a light she hadn’t seen in more than a year.

Mackenzie, the 1,500-ton tunnel boring machine drilling the three-mile-long Euclid Creek Tunnel 200 feet under Cleveland, broke through the shale at shaft 5, marking the end of her boring—but very exciting—journey.

While the tunnel boring machine is finished, the Euclid Creek Tunnel still has much work ahead. The tunnel will not be complete until 2015 as the lining and ongoing preparation is complete. When finished, the Euclid Creek Tunnel—one of seven huge Project Clean Lake tunnels—will hold 60 million gallons of sewage and stormwater and reduce pollution entering Lake Erie.

Video and details will be added as they become available.
