Fort Smith sits where the Poteau River meets the Arkansas River, right on the Oklahoma line, and the river shapes how traffic flows. I-40 runs east-west north of the river through Van Buren and Alma, and I-540 crosses the Arkansas from Van Buren into Fort Smith, curving around the east side toward the south end of the city. US 71 runs south toward Greenwood and the Ouachitas, and US 64 and US 271 lead west into Oklahoma.
Inside the city, Rogers Avenue is the main east-west commercial artery, running from downtown out past the hospitals and shopping toward I-540 and Barling. Towson Avenue carries traffic south, Zero Street crosses the south side, and Garrison Avenue anchors downtown with its wide historic main street. Midland Boulevard and Kelley Highway serve the north side and industrial areas. Rogers Avenue and the I-540 interchanges back up at rush hour, and trucking traffic is heavy on every major route.
Fort Smith Regional Airport sits on the southeast side, sharing its runways with the Air National Guard base, and its parking lots are a frequent no-start location. Chaffee Crossing, the redevelopment of the old Fort Chaffee land east of the city, keeps growing with new neighborhoods and businesses. Public transit is limited, so households depend on cars and pickups, and work vehicles keep the local industries moving. Because the city sits on a state line, plenty of drivers live on one side and work on the other, and a breakdown can happen anywhere along that daily loop.
