The project team is hosting an informational public meeting on December 6th at the Sioux Falls Convention Center from 6 pm to 8 pm. This meeting will allow the study team to gather public feedback and ideas as we work to finalize the study documents. The public informational advertisement can be viewed here.
All meeting materials presented at this public meeting will be posted no later than December 8th, 2016.

The Interstate 229 (I-229) Corridor through the City of Sioux Falls carries commuters and tourism traffic, provides access to the ever expanding east side of this thriving community, and allows direct access to downtown. The I-229 Major Investment Study will allow the City of Sioux Falls, the Sioux Falls Metropolitan Planning Organization, the South Dakota Department of Transportation, adjacent landowners, and area users to help determine the vision of the corridor. The I-229 Corridor Study Team will be using technology on this project that will allow us to distribute traffic in a manner that better mimics how delays during peak hour periods change driver behavior on our arterial streets and on I-229. Please become engaged in helping the study team work through this complex and dynamic study to learn what I-229 will become over the next 20 to 40 years.
A few things are going on right now: The study advisory team has identified a need to add Exit 7 (Rice Street) as Sub-study 5 and Exit 4 (Cliff Avenue) as Sub-study 6. Based on the initial findings additional study is required to determine what future improvements may be needed at those locations. We are also working on a higher level safety evaluation on the build alternatives that are still being considered for the sub-studies. As a result of the added sub-studies and the detailed safety analysis, the next public meeting will be delayed until the summer of 2016, when preliminary alternatives for Rice Street and Cliff Avenue will be presented. The next overall public meeting for all sub studies will take place late fall/early winter 2016, continue to check the website for updates. The following links will provide information as to which of the sub-study alternatives have been eliminated from further study.
Based on feedback from our December 2014 small group/business owners meetings, we have generated and then refined concept improvement options throughout the I-229 corridor. These concept improvement options are intended to accommodate future traffic volumes, at least to our year 2035 planning horizon.
The concept improvement options have been reviewed by the project Study Advisory Team and will be presented at our June 1 and 2 public meetings. We look forward to your feedback on these concept improvement options at these meetings or via responses to this web site. The concept improvement options will be posted on the web site on June 3, 2015.

The I-229 Major Investment Study team will begin investigating interchange improvements along
I-229 and corridor improvements on Minnesota Avenue, 10th Street, and Benson Road in the vicinity of I-229 starting in October, 2014. At our initial public meeting in October, 2013, we discussed using specialized modeling software to complete “Dynamic Traffic Assignment” (DTA) which would provide the most accurate means for us to observe how different alternatives being studied would impact traffic on specific corridors adjacent to I-229 or I-229 itself.
The DTA model is complete and is ready to be used to screen the alternatives that our team, and you as stakeholders, helped us generate as we work through alternative development phase. Looking back on the previously provided schedule, our team was optimistic that the process to develop and construct this complex model would take far less time. In reality, this model development phase took significantly more time than anticipated. We want to share the good news that the DTA model is complete and we can continue moving forward on the study tasks important to all of us.
Moving forward, we are identifying mid winter for small group/business owner meetings and late winter / early spring for our next public meeting. Meeting invitations will be sent out for all upcoming meetings. The small group/business owners meetings will be specific to the Minnesota Avenue, 10th Street, and Benson Road corridors, with one meeting held for each corridor. This will allow for feedback on improving safety and ideas for managing congestion. Thank you for your patience and our team looks forward to seeing you soon.
