Hampton Roads Bridge and Tunnel (HRBT) Expansion
Project Information
- Project Location:
- Norfolk, VA
- Status:
- Completed
- Structure Type:
- Bridge
Scope Of Work
HRBT is a three-and-a-half mile bridge-tunnel that runs between the cities of Hampton and Norfolk and connects the Peninsula and Southside Hampton Roads. During peak traffic season in the summer months, the bridge-tunnel transports over 100,000 vehicles per day, making this area one of the most congested in the state. The expansion will include replacement and/or improvement of over twenty-five bridge structures and will cover an area of 8,000ft across the Hampton Roads Waterway.
To complete the project by late 2025, land and tunnel work will occur simultaneously with a Tunnel Boring Machine (TBM) method of Construction. Once completed, twin two-lane bored-tunnels will be built west of the existing eastbound and westbound tunnels. Each tunnel will be approximately forty-five feet, creating the second largest tunnel opening for a TBM in North America. Additionally, the landside highway will be widened one mile in Hampton and four miles in Norfolk.
