CHESAPEAKE, Va. — The Hampton Roads Transportation Accountability Commission unanimously approved funding for the Hampton Roads Bridge-Tunnel expansion project on Thursday afternoon.

The historic funding agreement between HRTAC and the Virginia Department of Transportation will deliver the largest transportation project in Virginia's history, with a cost expected to be around $3.56 billion.

Earlier this year, Governor Ralph Northam awarded the project to Hampton Roads Connector Partners. They're expected to get the final contract in April.

The project will add two new two-lane tunnels, widen the four-lane sections of Interstate 64 in Hampton between Settlers Landing Road and the Phoebus shoreline, as well as the four-lane section of I-64 in Norfolk between the Willoughby shoreline and the I-564 interchange.
