This is a conventional tunnel in shale, lined with steel rings and wood lagging. Construction is projected to take 3 years and cost $100 million. If all goes well, the finished tunnel will be six miles long and will host a ten foot diameter reinforced concrete pipe.

why is there a new tunnel?

Is this the new water/sewage tunnel in Nky?

I can't remember the exact reasoning, but it is off of KY 20 in western Boone County near Petersburg.

New limestone mine?

Narrow-gauge, single-track light rail from Belleview to CVG Airport?

Fascinating stuff!

I thought it was probably the tunnel work being done by Sanitation District No. 1 of Northern Kentucky...what I don't understand is why this has been left unanswered by Eigth and State this entire time.  What's with the mystery?

 

  Sorry, I was away from the internet.

 

  Yes, it is a sewer tunnel for Sanitation District 1 of Northern Kentucky. This is the largest capital project that SD1 has ever had. It is designed to serve new development in Boone County. The portal is near Petersburg, Kentucky and if all goes well the boring machine will come out near Camp Ernst Road six miles east of there.

 

   

I don't like this project. They should be spending the money on speed bumps. $109 Million? We should have been able to vote against it.

I can't find a thread for this... sans this one. Feel free to move if there is one?

 

Sewage tunnel progressing smoothly

By Mike Rutledge, Kentucky Enquirer, March 28, 2010

 

COMMISSARY CORNER - The 65-ton Celtic Tiger tunnel-boring machine has been clawing faster almost every month since starting its six-mile journey across Boone County in late August.

 

By Friday morning the 193-foot-long machine - now grinding through shale and limestone 300 feet below the surface - had dug 228 feet farther during March than in February, its next best month.

 

"We're just about to have our best month ever," said England native John Swann, engineer's representative with the firm Hatch Mott MacDonald, which is overseeing the project. "This month already we've done 2,782 feet, and we've still got another four days."
