RICHMOND—Traveling the entire 55 miles of a new limited-access U.S. Route 460 between Suffolk and Petersburg could cost between $5.50 and $11 one way. That’s by car. For trucks, the toll could be as high as $22.

The Virginia Department of Transportation has reviewed three conceptual proposals from companies to develop and operate a new U.S. Route 460. The design-build price ranges from $1.44 billion to $1.8 billion in current year figures.

The proposals from 460 Partners, MultiModal Solutions and Cintra Infraestructuras request a minimum term of 75 years to develop, construct, operate, maintain and collect tolls on a new Route 460, which would be built south of the existing highway.

Proposals from 460 Partners and MultiModal Solutions envision a five-year construction period. Cintra Infraestructuras’ proposal plans a construction phase of 5 1/2 years. Tolls, according to the conceptual proposals, would be collected electronically.

Each of the proposals also calls for tolls to escalate at a rate between 1.92 and 3 percent per year.

The next step, according to VDOT, is a review by an independent panel to be appointed by the secretary of transportation. The review process will include public participation, according to the agency.

Gov. Bob McDonnell and VDOT officials have called the U.S. Route 460 project a high priority because of its importance as an emergency and hurricane evacuation route, for strategic military connectivity, the safety of the traveling public and the movement of freight in and out of the Hampton Roads ports.
