Illinois is probably the busiest state in the Midwest, with the metropolitan area of Chicago being a major Illinois freight shipping hub. There is a major port here that connects the Great Lakes to the Mississippi river, allowing for inexpensive water transport. Illinois freight shippingby rail is also very inexpensive and easy to use, as Chicago is one of the largest railroad hubs in the country. There is also an extensive highway system that helps move the high volume of goods produced in Illinois from agriculture, meat and dairy production, and energy production. LTL freight shipping is usually quite affordable due to the high volume of goods moving in, out, and through the state.
