Black River Tunnel
On January 17th 2012, the Lorain City Council approved a $20,732,954 contract with Walsh/Super Excavators JV for the Black River Conveyance & Storage Tunnel. This infrastructure improvement program was designed to eliminate sanitary overflows to the Black River. Walsh/Super Excavators is currently constructing approximately 5,500 linear feet of 23-ft diameter rib and bored, two-pass, TBM Rock Tunnel. The final tunnel is a 19-ft ID storage tunnel that extends approximately 120 feet below ground and along the bank of the Black River. The TBM was launched from a 36-ft ID, 175-ft deep shaft which will serve as home to the future Pump Station. The machine reached the 30-ft ID, 115-ft deep receiving shaft on April 29th, 2014. Final project completion was reached in the Spring of 2015.
