How did the United States benefit from Thomas Pickney's treaty?

This Treaty defined the border with Spain and the US

Explanation:

The Treaty was signed and defined the US territorial debates that were ongoing in between the countries. It is considered a diplomatic success for the US and garnered US citizens access to travel the Mississippi River freely and access trade routes from the port in New Orleans in Spanish control.
