Hampton and Norfolk
The I-64 Hampton Roads Bridge-Tunnel in southeastern Virginia has long been one of the region’s most congested corridors. The existing 3.5-mile facility consists of two 2-lane immersed-tube tunnels on artificial islands, with trestle bridges to shore. These tunnels opened in 1957 (current westbound lanes) and 1976 (eastbound lanes) and are approximately 7,500 feet long. Traffic on these four lanes exceeds 100,000 vehicles per day during peak summer traffic.
The Hampton Roads Bridge-Tunnel Expansion project will ease this congestion by widening the four-lane segments of the I-64 corridor in the cities of Hampton and Norfolk.
In 2014, the Hampton Roads Transportation Accountability Commission (HRTAC) included a Hampton Roads Crossing Study in its list of priority projects, leading to the development of a Supplemental Environmental Impact Statement (SEIS) to evaluate options for this crossing.
In December 2016, the Commonwealth Transportation Board approved “Alternative A” as the preferred alternative, laying the groundwork to complete the SEIS. The Federal Highway Administration approved the SEIS in April 2017 and issued a Record of Decision in June 2017, enabling VDOT to proceed with more detailed design and procurement of the project.
Alternative A consists of improvements to the I-64 corridor between I-664 in Hampton and I-564 in Norfolk to provide consistent six-lane capacity throughout the corridor. This work includes a new Hampton Roads crossing generally parallel to the existing Hampton Roads Bridge-Tunnel. In addition to tunnel and marine bridge work, the scope for Alternative A also includes pavement and structure widening, bridge reconstruction, drainage improvements and noise walls.
Within the limits of the environmental study, the engineering and construction community will have latitude to propose innovative design approaches and construction methods that most cost-effectively meet the project’s purpose and need. For instance, the study does not stipulate any particular tunnel-construction method nor require a specific alignment.
The Virginia Department of Transportation (VDOT) is conducting outreach to the engineering and construction community to share available project information and seek feedback for shaping the anticipated procurement. Additional information is available here.
