Indiana is a largely flat state with agriculture and steel industries. The roads are usually well-maintained, and much Indiana freight shipping is done via truck. The state does not have a large international airport, and most goods need to be trucked out of the state for air shipping. As the state borders the Mississippi River as well as the Great Lakes, a large of amount of Indiana freight shipping also moves by water. The railroad system in this state is extensive and well-maintained. With plenty of freight moving in and out of the state, Indiana freight rates are very affordable.
