Knoxville is the third-largest city in the state of Tennessee, located in the eastern part of the state. It is known for its rich history and scenic beauty, nestled in the foothills of the Great Smoky Mountains. The city was named after Henry Knox, the first Secretary of War under President George Washington. Knoxville played a significant role in the transportation of goods during the early days of settlement, as it was a key location for river and rail transportation. The Tennessee River flows through the city, providing a vital waterway for the movement of freight. Today, Knoxville is still an important transportation hub, with a well-connected network of highways and rail lines.

One of the most notable transportation landmarks in Knoxville is the Henley Street Bridge. Built in 1931, it is one of the oldest vehicular bridges in the city and spans the Tennessee River. The bridge has undergone several renovations and improvements over the years to accommodate the increasing traffic demands. It serves as a major thoroughfare for freight transportation, connecting downtown Knoxville with the south side of the city. The Henley Street Bridge offers stunning views of the river and the surrounding mountains, making it a popular spot for locals and tourists alike.

St. Louis, Missouri, known as the "Gateway to the West," has a rich history in freight transportation. The city's strategic location along the Mississippi River made it a crucial hub for trade and commerce in the 19th century. In fact, St. Louis was the largest inland port in the United States during that time, with steamboats and barges ferrying goods up and down the river. The city's prominence as a transportation hub continued with the development of railroads in the late 19th and early 20th centuries, further connecting St. Louis to the rest of the country.

One of the most iconic symbols of St. Louis is the Gateway Arch, which stands at 630 feet tall and is the tallest man-made monument in the United States. The arch was built as a monument to the westward expansion of the United States and serves as a reminder of St. Louis' historical role as a gateway for people and goods traveling westward. Today, St. Louis remains an important transportation hub, with a major international airport and an extensive network of highways and railroads that facilitate the movement of goods and people throughout the region.
