A huge new tunnel expansion project in Virginia is expected to cost US$3.8 billion, making it the biggest highway works planned in the state. The Hampton Roads Bridge-Tunnel (HRBT) Expansion project is being managed by the Virginia Department of Transportation (VDOT).
The work will see a 16km stretch of the I-64 route being widened, boosting capacity and cutting congestion. Additional lanes will be added in either direction along the route while bridges will be changed and junctions upgraded.
