# Northeast Ohio District Awards Tunnel Contract

The Northeast Ohio Regional Sewer District awarded a Granite–Super Excavators joint venture an approximately **$324.8 million** design-build contract for the Big Creek Tunnel in the Cleveland area. Construction is scheduled to begin in autumn 2026 and finish by winter 2030. The work is the final phase of the district’s $3 billion Project Clean Lake program and is expected to reduce combined sewer overflows by about 550 million gallons annually.

- The award covers major tunnel and sewer infrastructure, making tunneling, design-build delivery, and related construction capabilities central to the project.
- Because the contract has been awarded, contractors can use its scale and delivery model as a reference when evaluating future municipal wastewater and tunnel projects; the signal does not identify an open solicitation or subcontracting opportunity.
- The schedule places construction commencement in autumn 2026, with completion planned for winter 2030.
