(J. Bennett Johnson Waterway)
Currently, the Red River is navigable to Shreveport, Louisiana. A U.S. Army Corps of Engineers (USACE) study has been done to allow navigation into Arkansas to Index Bridge (between Texarkana and Ashdown, Arkansas). There are also variations calling for navigation to Garland City and Fulton, Arkansas. Each study has a determining cost/benefit ratio; unfortunately, the ratio does not meet the minimum requirement set by USACE.
