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.  The South Island is percolating with activity to prepare the island for the massive Tunnel Boring Machine (TBM) which will bore twin tunnels parallel to the existing tunnels.   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.     Please subscribe to our podcast!
