ROANOKE, Va. -

Governor Bob McDonnell announced Friday morning that changes are coming to some major interstates in Southwest Virginia.

According to a news release, the Virginia Department of Transportation is moving forward with technology upgrades designed to improve safety and traffic flow on some major interstates, including Interstate 64 over Afton Mountain.

Upcoming improvements for I-64 will be part of a project located between mile markers 94 and 107 through Augusta, Nelson, and Albemarle Counties.

Changes will include message signs to keep drivers informed of traffic changes and weather conditions, additional traffic cameras to allow surveillance of the corridor, visibility detection sensors to improve the existing fog-light system, and fiber-optics infrastructure to support future development of variable speed limits based on weather and traffic conditions.

The changes are part of an Active Traffic and Safety Management System project, expected to cost $4.6 million. The Commonwealth Transportation Board awarded the $4.6 million contract to G4S Technology of Springfield to design and build the ATSMS.

A similar ATSMS project on Interstate 77 in Carroll County has also been proposed.
Construction on the Interstate 64 Afton ATSMS project will begin in early 2014 and is scheduled to conclude in summer 2015.
