Tulsa Port of Catoosa & Maritime Education Center

The Port of Catoosa's distinction as the furthest inland ice-free international seaport in America is not a marketing claim — it is a literal geographic fact. The McClellan-Kerr Arkansas River Navigation System, completed in 1971, extends 445 miles from the Mississippi River at the mouth of the Arkansas River upriver through a series of locks and dams to the port at Catoosa. Cargo shipped from the Port of Catoosa moves via barge through the system to the Mississippi, down to New Orleans, and out to global ocean shipping — a route that allows Oklahoma businesses to ship product to international markets without the cost of overland trucking to a coastal port.

Roughly 90% of the cargo that moves through the port is agricultural — primarily soybeans, wheat, and fertilizer — with the remaining 10% being manufactured goods, steel, petroleum products, and bulk commodities. The total economic activity supported by the port across northeast Oklahoma is in the billions of dollars annually and includes manufacturing, agricultural processing, transportation logistics, and direct port employment.

The 2,500-acre port complex includes barge docks, container terminals, rail connections, and an industrial park that houses more than 70 businesses ranging from grain elevators and steel fabricators to manufacturing facilities and chemical processors. The mix of heavy industry and active river commerce gives the port a working-port atmosphere that is unlike anything else in Oklahoma — visitors who arrive expecting a quiet recreational port are surprised by the genuine industrial scale.

The Oklahoma Maritime Education Center is a free public museum located within the port complex and is the natural starting point for a visitor's exploration. The Center includes interactive exhibits on the history of the McClellan-Kerr Navigation System, working models of locks and dams that demonstrate how the system raises and lowers barges across the elevation difference between Tulsa and the Gulf, historical photographs and artifacts from the system's construction in the 1950s and 1960s, and information on current port operations.

The Center's signature exhibit is the M/V Charley Border — a real working towboat that is permanently dry-docked immediately adjacent to the Education Center building. Visitors can climb aboard, walk through the wheelhouse, see the engine room, and experience the scale of inland-waterway towing operations firsthand. The dry-docked display is one of the most distinctive maritime museum experiences in the central United States given how rare river towboats are as public exhibits.

The Center is operated in cooperation with the Arkansas River Historical Society, the nonprofit organization established to preserve and interpret the history of the McClellan-Kerr Navigation System and Oklahoma's inland-waterway commerce. Admission is free; donations support ongoing operations and exhibit maintenance. The Center is open Monday through Friday from 8am to 4:30pm — note that the weekday-only schedule is the main constraint for weekend visitors.

The port complex is open to public visitation via the self-guided driving tour. The tour route is published on the tulsaports.com website and is also available as a printed map at the Maritime Education Center. The route winds through the industrial park with interpretive signage describing the various port operations, the major industrial tenants, and the navigation system infrastructure visible from the road.

Highlights along the driving tour include the main barge docks (where visitors can often see barges being loaded or unloaded), the grain terminals (massive elevators that handle the millions of bushels of soybeans and wheat that move through the port each year), the container and bulk-cargo terminals, and several of the major industrial tenants whose operations are visible from public roads. The tour takes roughly 45 to 60 minutes by car at a relaxed pace.

Photography is permitted throughout the public-access portions of the port. Note that some areas are restricted access (active rail operations, certain industrial facilities) and are marked with signage; the self-guided tour route avoids those areas and stays in publicly-accessible zones. Guided group tours can also be arranged by appointment through the port's office (call ahead 24-48 hours).

Beyond the self-guided driving tour, the port offers guided group tours Monday through Friday from 9am to 4pm by appointment. The guided tours are typically 90 minutes to two hours and include a stop at the Maritime Education Center, a driving tour through the port with a knowledgeable guide, and access to areas not on the self-guided route (sometimes including a closer look at active barge loading operations, depending on tenant operations on the day of the tour).

Group tours are popular with school groups, scout troops, civic organizations, university classes, and engineering professional groups interested in the inland-waterway infrastructure. The tours are free but require advance scheduling. Group leaders should call the port's main office (918-266-2291) to arrange a tour and confirm timing.

The Maritime Education Center also hosts occasional special events — author talks on inland-waterway history, school-program field days, and Route 66 Centennial programming in 2026 that connects the port's history to the broader story of Catoosa as a transportation crossroads.

The Tulsa Port of Catoosa pairs naturally with a Catoosa-focused day. The Maritime Education Center's Monday-through-Friday morning hours make it the best first stop on a weekday Catoosa itinerary: arrive at the port by 9am, spend 60 to 90 minutes at the Maritime Education Center and Charley Border, drive the self-guided port route for another 45-60 minutes, then continue to the Blue Whale and the D.W. Correll Museum for the afternoon.

Weekend visitors who can't access the Maritime Education Center should still consider the self-guided driving tour where accessible. The port complex is visually impressive even without the Education Center context, and the working barge operations on the Verdigris are genuinely interesting to watch. The driving tour adds about an hour to a Catoosa day without requiring any reservations or arrangements.

For Route 66 road-trippers interested in transportation history, the port is a particularly satisfying complement to the Mother Road experience. The Route 66 era was one chapter in northeast Oklahoma's transportation history; the McClellan-Kerr Navigation System and the Tulsa Port of Catoosa represent another. Seeing both in the same day produces a richer understanding of how Catoosa has functioned as a regional transportation crossroads across multiple eras.
