Intersection improvements at developments
throughout wisconsin

Intersection improvements can be required when there is development along the corridor of a major arterial highway. Often the roadway's governing agency will first require a developer to perform a Traffic Impact Analysis (TIA) for the proposed site.  The TIA helps planners understand how much traffic will be generated by the new development.   Whether the development is residential, business, commercial or industrial, in most cases, it will create additional traffic for the existing highway.  As a result, off-site modifications might be needed to existing intersections within the project corridor. These TIA intersection improvements typically include adding turn-lanes and driving lanes, extending existing turn-lanes to provide more storage, and widening curb radii to allow truck turns.  In some cases, installation of a traffic signal is also required.   These relatively minor geometric changes can become complex when right-of-way is needed, when private utilities are affected, or when multiple reviewing agencies have a stake in the off-site improvements.
