Texarkana

Texarkana is a city in the U.S. state of Arkansas and the county seat of Miller County, on the southwest border of the state. As of the 2020 census, it had a population of 29,387. It is the twin city of Texarkana, Texas, located just across the state line. The city was founded at a railroad intersection on December 8, 1873, and was incorporated in Arkansas on August 10, 1880. Texarkana and its Texas counterpart are the principal cities of the Texarkana metropolitan area, which in 2021 was ranked 289th in the United States with a population of 147,174, according to the United States Census Bureau.

Within the Ark-La-Tex subregion of southwest Arkansas, Texarkana is located in the Piney Woods, an oak–hickory forest that dominates the flat Gulf Coastal Plain. Texarkana's economy is based on agriculture. The city has long been a trading center, first located at the intersection of major railroads serving Texas, Arkansas and north into Missouri. Since then three major Interstate highways constructed crossroads here: Interstate 30 (I-30), I-49, and the future I-69. The Red River Army Depot is the largest single employer in the city.
