Granite Construction Company secured the USD215 million contract for the Northside Interceptor Tunnel project, whose design was completed in the Spring of 2023.  The City of Akron (Ohio, USA) performed a pre-qualification process, with four contractors selected to submit proposals.  

The Northside Interceptor Tunnel Project is one of the final projects of the EPA mandated Consent Decree, entered in 2014, to improve the City’s sewer infrastructure and reduce combined sewer overflows (CSOs). This project consists of constructing a 5.3 m (16.5-foot) internal diameter tunnel.  The tunnel will collect and store CSOs from four overflow locations, which are located along the Cuyahoga River.  The tunnel route follows Riverside Drive from Cascade Valley Metro Park – Chuckery Area to Front Street.  It will be 2,030 m (6,660 feet) long, over 30 m (100 feet) below ground in rock, and will be able to store over 38 million liters (10 million gallons) of combined flow. The project is planned to begin in September 2023 and is expected to be completed in July 2027.Visit  https://investor.graniteconstruction.com/ and https://www.akronwaterwaysrenewed.com/. 34/23.
