Welcome to I-29 Corridor Study

As part of their program of monitoring and management of the state system, the SDDOT is completing a study of the I-29 corridor from US 18 (Exit 62) through the Tea interchange (Exit 73). The purpose of this study is to identify what improvements are needed in the corridor (to both interchanges and the I-29 mainline) and develop a timeline for implementing proposed improvements.
