Interstate Highway System Main Auxiliary Suffixed Business Future

Interstate 74 is an Interstate Highway in the United States. The main part of it goes from Davenport, Iowa east to Cincinnati, Ohio and will be extended to South Carolina. There are three parts of Interstate 74 that are in North Carolina, with no part being connected now but will be. The highway will not be continuous because the southeastern part will only be built in North and South Carolina. Interstate 74 was 428.81 miles (690.10 km) long as of 2025.^[1]
