The city is divided by the State Line Avenue, with the Texas side being known as Texarkana, TX and the Arkansas side as Texarkana, AR. This division gives Texarkana the distinction of being the only city in the United States that is located in two different states and two different counties.

Texarkana has a rich history in the transportation industry, particularly in freight transportation. The city is strategically located at the intersection of major highways, including Interstate 30 and Interstate 49, making it a crucial hub for the transportation of goods. The Texarkana Rail Yard, operated by Kansas City Southern Railway, is one of the largest rail yards in the region and plays a vital role in the movement of freight. Additionally, Texarkana is home to the Texarkana Regional Airport, which serves as a transportation hub for air cargo and freight.

Davenport is a city located in eastern Iowa, along the Mississippi River. It is the third largest city in the state and is part of the Quad Cities metropolitan area, which also includes the cities of Bettendorf, Iowa, and Rock Island and Moline in Illinois. Davenport was founded in 1836 and quickly grew as a major trading hub due to its location on the river. In the late 19th century, the city became a center for the lumber industry, with many sawmills and factories being established along the riverfront.

One of the key factors that contributed to Davenport's growth and prosperity was its role in freight transportation. The city became an important transportation hub, with railroads and steamboats connecting it to other parts of the country. The Mississippi River served as a major artery for transporting goods, and Davenport's location made it a key stop along the river. The city's riverfront was lined with warehouses and docks, where goods were unloaded from steamboats and transferred onto trains for further distribution. Today, Davenport remains an important transportation hub, with a modern port facility that handles a variety of cargoes, including agricultural products, steel, and machinery.
