Interstate 75 (I-75) is a major north-south Interstate Highway in the eastern United States. Spanning approximately 1,786 miles, it is one of the longest highways in the Interstate Highway System and runs from Hialeah, Florida, near Miami, to Sault Ste. Marie, Michigan, at the Canadian border.

Route description

I-75 is a key highway serving the Eastern and Midwestern United States, facilitating major metropolitan areas such as Atlanta, Detroit, and Tampa. The highway begins in the south at US 1 in Hialeah, Florida, and travels northward through the Florida Peninsula, entering Georgia, where it passes through Atlanta. Continuing north, it crosses into Tennessee, Kentucky, Ohio, and Michigan, before terminating at the Canadian border in Sault Ste. Marie.

Major junctions

Throughout its route, I-75 intersects several major highways, including Interstate 10 in Florida, Interstate 20 in Atlanta, Interstate 24 in Chattanooga, and Interstate 70 in Ohio. These junctions are critical for regional connectivity and are among the busiest segments of the highway.

History

Construction of I-75 began in the 1950s, with the highway officially designated in 1957 as part of the original Interstate Highway System. The route was completed in segments, with the final section in Michigan opening in the 1970s. Over the decades, I-75 has undergone numerous expansions and improvements to accommodate increasing traffic and enhance safety.

Economic impact

I-75 plays a vital role in the economy of the regions it serves by facilitating the movement of goods and people. It is a crucial corridor for commerce, particularly for the automotive industry in Michigan and agricultural products in the southern states.

Future developments

Plans for upgrading and expanding I-75 continue to evolve, including projects to widen the highway, improve interchanges, and enhance traffic management systems to reduce congestion and improve safety.
