Specifications include, but are not limited to: The base scope of the Project (the “Base Scope”) will consist of the design and construction of improvements along approximately nine (9) miles of the I-64 corridor between Settlers Landing Road in Hampton (Exit 267) and I-564 in Norfolk (Exit 276). The Base Scope includes a new bridge-tunnel crossing, approximately 3.5 miles long and generally parallel to the existing Hampton Roads Bridge-Tunnel, and replacement of the existing marine approach bridges between the Hampton Roads Bridge-Tunnel islands and the shorelines. On land, the Base Scope includes the addition of a third lane to I-64 in each direction, with a roadway section sufficient to accommodate a part-time median shoulder lane. For the marine crossing, the new bridge-tunnel complex will accommodate four (4) lanes of traffic for a total of eight (8) lanes of capacity across the water.
