Budget estimate

$10,000,000 – $50,000,000

The budget for this project is difficult to estimate without more information on the scope and requirements of the Lower Olentangy Tunnel Phase 2 project. However, considering the complexity and scale of tunnel construction projects, the budget could potentially be in the range of $10 million to $50 million, depending on factors such as the length and depth of the tunnel, materials used, and labor costs.
