Interstate 229 Descriptions


South Dakota:
I-229 begins at a trumpet interchange with I-29 just south of Globe University. I-229 travels to the northeast, passing north of the Avera Heart Hospital of South Dakota before going through several parks. A few miles to the northeast, I-229 turns north and passes through metropolitan Sioux Falls. I-229 terminates at a partial cloverleaf interchange with I-90.


I-229 currently has a partially complete cloverleaf at its northern terminus. SDDOT wants to improve this interchange to provide all movements, or at least improve its overall flow with Interstate 90. The discussion is merely on improving the interchange and not about extending the highway further north.
