Budget estimate

$20,000,000 – $30,000,000

Based on the project's scope and complexity, the estimated budget for this project could be around $20 million to $30 million. This estimate is based on the fact that the project involves the construction of bridges, a roundabout, and roadway approaches, which typically require significant resources and labor. Additionally, the project's deadline is June 21, 2028, which suggests that the contractor will need to work efficiently to complete the project on time. The estimated budget range takes into account the costs of materials, labor, equipment, and other expenses associated with the project.
