 DDI Video Tutorial https://www.youtube.com/watch?v=1pMopeJp1Uk This video shows an animation of a proposed DDI for another WisDOT project on WIS 11 at I-39 in Janesville Wisconsin.  WisDOT DDI Information http://wisconsindot.gov/Pages/safety/safety- eng/inter-design/ddi.aspx 11

Why selected?  Best operational quality for the primary movements (yellow arrows shown on figure).  Most favorable comments during the fall 2015 public outreach.  Requires least additional right-of-way (8.4 acres)  Most reserve capacity for high-traffic conditions.  Provides desirable trade-off between cost, property impact, and operational quality. Estimated cost including real estate: $28-29 Million 12

Drainage to Lake Pacawa  Investigating drainage techniques to minimize impacts along County B  Storm sewer water put into pond north of Lake Pacawa  Pond then discharges cleaned water into pipe to Lake Pacawa Storm water  Temporary construction pond location impacts to Worzella Pines Park Worzella Pines Park Lake Pacawa 13
