I-90/I-229, Sioux Falls, SD

I-90 goes east-west here, I-229 heads off to the south. SD 115 is just off the west edge of this map.

I-229 forms a south and east side beltline around the fast growing Sioux Falls, SD metro area. Its connection with I-90 is interesting in that if one continues northward from I-229 through the interchange, he or she will immediately continue onto an unpaved local farm road. This road continues northward paralleling and 1.6 km east of SD 115 (former US 77) for 20 km to the Dell Rapids, SD area.

US 16 through here was decommissioned when the last section of I-90 was completed in the Blue Earth, MN area in 1977.

I-229 is clearly intended to continue northward from I-90, most likely as a completed I-29 'beltline' of Sioux Falls, as there is room reserved for completing the cloverleaf interchange. With the rapid growth of the Sioux Falls area in recent years, this might be in the offing in the mid-term future.

Until then, just don't miss that last exit.
