Fort Smith’s historic role as a gateway for transportation returns to the spotlight with the ambitious Slackwater Harbor project in Van Buren.
This $18.16 million development, supported by a major federal grant, aims to build a modern harbor with the ability to dock up to eight barges simultaneously and significantly expand freight capacity along the Arkansas River.
Construction is set to begin in April 2026 and wrap up by early 2027, promising new jobs and industrial opportunities for the region.
The project draws on a tradition—dating back to the Butterfield Overland Mail and steamboat era—of using the river as a lifeline for commerce and connection.
Once complete, Slackwater Harbor is poised to reduce congestion, make shipping more efficient, and strengthen the River Valley’s place in the nation’s trade network.
