I-229 EXIT 6 (10th STREET) CROSSROAD CORRIDOR STUDY
The 10th Street Interchange at I-229, along with the 10th Street Corridor in Central and Eastern Sioux Falls, carries between 20,000 and 30,000 vehicles per day with growth taking place along this corridor every year. From downtown, east to the proposed SD 100 Corridor, managing growth will be tricky and costly. Most businesses along the corridor already feel that they don’t have enough property so developing options to prepare this area for growth will be a cooperative effort by the Study Team, corridor users, and adjacent landowners.
In 2013 and 2014, a study will be conducted to determine ways to:
Reduce traffic congestion along 10th Street and at the Interchange.
Develop a plan for managing the growth along the corridor.
Improve pedestrian mobility.
Expand the roadway to meet capacity requirements while minimizing private land needs.
Improve the intersection of 10th Street and Cleveland Avenue.
Improve safety and reduce accident potential.
Accommodate special events that could affect traffic levels from downtown to I-229.
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.
