Seventy-two miles of the four-lane highway in western Kentucky, connecting Owensboro and Bowling Green, is now interstate 165.
The change was announced by Gov. Matt Bevin and Congressman Brett Guthrie in 2016. Necessary safety upgrades, like pavement, bridge walls, guard rails, and rock slopes, are being made along the route. But most noticeable to drivers is the changing of signs and new exit numbers.
