Tulsa is the second-largest city in the state of Oklahoma and is known as the "Oil Capital of the World." The city's economy was built on the success of the oil industry, which boomed in the early 20th century. Tulsa became a major hub for oil production, refining, and transportation, with numerous oil companies establishing their headquarters in the city. The oil industry played a significant role in shaping Tulsa's skyline, with many iconic Art Deco buildings constructed during this time.

Freight transportation is a vital part of Tulsa's economy, as the city is strategically located at the crossroads of major highways and rail lines. Tulsa is served by several interstate highways, including I-44, I-244, and the historic Route 66. These highways connect Tulsa to other major cities in the region and facilitate the transportation of goods and materials. The city is also served by the Tulsa Port of Catoosa, which is the furthest inland seaport in the United States and provides access to international trade via the McClellan-Kerr Arkansas River Navigation System.

Port Arthur, located in Jefferson County, Texas, is a city with a rich history in the freight transportation industry. The city's strategic location on the Gulf of Mexico has made it a major hub for shipping and trade. Port Arthur is home to one of the largest deep-water ports in the United States, the Port of Port Arthur. This port handles a wide range of cargo, including petroleum products, chemicals, and agricultural commodities. It is also a key gateway for international trade, with connections to countries all over the world.

In addition to its port, Port Arthur is also known for its extensive network of railways. The city is served by several major rail lines, including Union Pacific and BNSF Railway, which provide crucial connections to the rest of the country. These rail lines transport a variety of goods, such as crude oil, natural gas, and manufactured products. The presence of these rail lines has played a significant role in the economic development of Port Arthur, attracting industries and creating job opportunities.

Port Arthur's history in the freight transportation industry dates back to the early 20th century. The discovery of oil in the nearby Spindletop oil field in 1901 led to a boom in the city's economy and the establishment of the Port Arthur Refinery, one of the largest oil refineries in the United States. This refinery, along with others in the area, has contributed to the growth of the petrochemical industry in Port Arthur. Today, the city continues to be a major player in the energy sector, with numerous refineries, chemical plants, and storage facilities.
