“The Ohio Canal Interceptor Tunnel is being honored for its successful completion through challenging ground conditions while demonstrating new technology in the United States,” said Dr. Levent Ozdemir, course director for the Breakthroughs in Tunneling Short Course. “This project will help improve the water quality in the area, while contributing to the community by using local labor, subcontractors and suppliers.”

The Ohio Canal Interceptor Tunnel (OCIT) was built by the City of Akron (OH) as part of its $1.4 billion CSO-reduction program. The tunnel will store more than 25 million gallons of combined sewer flows and will prevent an estimated 450 million gallons of overflows from entering waterways annually.

The main component of the project is a 27-ft diameter, 6,240-ft long tunnel that begins at a portal adjacent to the Little Cuyahoga River and ends at a shaft downtown. The project was completed through soft-ground, mixed face and rock zones using a Robbins Crossover XRE TBM, the first use of the technology in the United States.

In 2015, the joint venture of Kenny Construction and Obayashi was awarded the project with a winning bid of $184.1 million. Notice to proceed was issued on Nov. 4, 2015. The machine launched Oct. 18, 2017, and completed its drive Aug. 29, 2018.
