Construction Cost: $70,000,000

As the Prime Consultant, The Hanna Group was trusted to provide full construction management services for the Cosumnes River Boulevard Extention/I-5 Interchange project. This project will extend Cosumnes River Boulevard from Franklin Boulevard to an Interchange at I-5, and then farther west to an at-grade intersection with Freeport Boulevard in the currently unincorporated town of Freeport. This mega project includes the construction of a bridge that will cross over Morrison Creek and UPRR, as well as the demolition and reconstruction of the current overpass over I-5.

Not only will the completion of this large scale construction project reduce traffic delays and congestion, it will also support economic development in the area and revitalize communities along the corridor.
