By 2024, a new interstate will stretch from the Canadian border in Michigan to the Indiana-Kentucky line thanks to a $1.5-billion highway and reshielding project.
Interstate 69 was first pitched in the 1940s as a single, continuous route from the Texas-Mexico line to Canada. While states such as Louisiana and Mississippi still seek federal money before starting their portions of the border-to-border highway, Indiana is closing in on finishing its part of I-69 that started in 1971.
