Interstate 229

Interstate 229 is a 12-mile loop around Sioux Falls. This runs from a junction with Interstate 29 near the Minnehaha/Lincoln County Line on the southwest side of Sioux Falls, to the northeast corner of Sioux Falls, at Interstate 90.

What makes this highway interesting is the northern end point. After the ramps to I-90 it runs into a Township Road. Less than a quarter mile from the ramp to westbound I-90 the pavement changes to a gravel surface.

While in South Dakota, I-229 is not multi-plexed.
