The South Dakota Department of Transportation (SDDOT) and its partners are studying Exit 86 on Interstate 29 to determine what modifications might be needed at this interchange to accommodate future growth and traffic volumes.
Planning Study Goals
- Develop an Interchange Modification Justification Report for the Federal Highway Administration
- Create Environmental Screen Report and National Environmental Policy Act documents for future planning
- Provide guidance to implement recommended improvements for future construction
Interchange Options
The project teams will be analyzing two interchange examples that were identified in the SDDOT 2020 Decennial Study. Additionally, up to two additional options will be identified and analyzed as part of the study.
Option 1: Bridge Widening and Turn Lanes
Coming soon!
Option 2: Single Point Urban Interchange (SPUI)
Coming soon!
Timeline
Interchange modifications require various studies and screening reports. This project begins with data collection and analysis to help us develop and refine modification options. Next is the development of the Interchange Modification Justitification Report (IMJR) and Environmental Screening Report (ESR). A more detailed Environmental Analysis occurs during the National Environmental Policy Act (NEPA) process. Lastly, an interchange design is finalized. This design will kick-off the construction phase of this project.
