Interstate 229 (I-229) is a 15-mile-long (24 km) auxiliary Interstate Highway that runs through Saint Joseph, Missouri. It begins southeast of the city at I-29 and U.S. Route 71 (US 71) and travels to the northwest into the city. In St. Joseph, it runs with US 59. Just north of an interchange with US 36, the two routes travel over a one-mile-long (1.6 km) viaduct on the banks of the Missouri River. The two routes split at the north end of the viaduct. The interstate ends at another interchange with I-29 and US 71 north of St. Joseph.

The interstate was built in the late 1970s and early 1980s and was intended to draw people into St. Joseph's downtown area. A portion of the historic Robidoux Row, an area of St. Joseph built by the towns founder, was demolished to make way for the viaduct along the Missouri River.

I-229 begins southeast of Saint Joseph at a directional T interchange with I-29 and US 71 in rural Buchanan County. It heads to the north-northwest and almost immediately meets Route A at a half-diamond interchange; in this case, only southbound I-229 traffic can access Route A and Route A traffic can only access northbound I-229. North of the highway is a housing development while there are fields to the south. Another half-diamond interchange provides access to Route 752. Northbound I-229 traffic may exit to reach westbound Route 752. Full access to Route 752 is provided by the next exit, Route 371, known locally as 22nd Street.
