New Corridor Concepts
Construction of new SH-8 highway alignment in rural area between Moscow and Troy with a consistent two-lane or four-lane cross section with shoulders and clear zone to current design standards. Other concepts, such as passing lanes, vehicle pullout areas, and turn lanes, would be installed with the new highway alignment to optimize traffic operations and safety.​
