Preparing for the TBM

As the Design-Builder for Virginia's largest construction project awaits Notice to Proceed, early work is underway on the Hampton Roads Bridge-Tunnel Expansion Project.

In the latest installment of HRBT Tunnel Talk, Paula Miller talks with Project Director Jim Utterback about the significant effort it takes to obtain such a large permit, and she learns about 8 months of preliminary island work from Xavier Billy, the Construction Manager for the Tunnel Approach Structures.
