Tri-State Incident Management Team 

The Tri-State Incident Management Team (TSIMT) was formed in 2003 by the Iowa DOT.  The purpose of the group is to discuss incident management within the tri-state metropolitan area. More specifically the group communicates about upcoming events that might affect traffic, coordinates dynamic message boards, communicates about upcoming construction/maintenance plan, communicates upcoming enforcement activity, reviews past incidents and determines what was done well and what can be done better and develops and maintains the Tri-State Incident Management Plan. Current members of the group include representatives from the following agencies: Iowa DOT, Nebraska DOR, South Dakota DOT, SIMPCO, law enforcement from IA, NE, SD,  fire department, emergency management, 911 communication center, county engineers, city officials, public transit and tow truck companies.  The group currently meets on a monthly basis.

Tri-State Incident Management Plan -  This proposed Highway Detour Plan covers the primary highway networks of Interstates 29 & 129, and US 77, US 75 and US 20 within the tri-state area of South Dakota, Nebraska and Iowa. The purpose of the plan is to provide standardized details of detour proposals and agency contacts when an incident occurs resulting in the need to close lanes or detour traffic for various routes in the tri-state area.  The primary users of the plan are fire, law enforcement, EMS, County Road Departments, City Street Departments, and Department of Roads/Department of Transportation personnel.
