The Colorado Border is the boundary that separates the state of Colorado from its neighboring states. It is approximately 1,000 miles long and features diverse landscapes, including mountains, plains, and rivers. The border touches Wyoming to the north, Nebraska to the northeast, Kansas to the east, Oklahoma to the southeast, and New Mexico to the south. This border is significant for various reasons, including trade, travel, and cultural exchange. Major highways, such as Interstate 25 and Interstate 70, cross the border, facilitating transportation and commerce. The border also plays a role in defining regional identities and state governance.
