Intersection Control Evaluation
The purpose of the Intersection Control Evaluation, or ICE study, is to determine which type of intersection control (Stop, Yield, or Signalized) is best stuited for the conditions. For this project it was found without exception signalized intersections controlled.
Preliminary Environmental Analysis Report
The purpose of the Preliminary Environmental Analysis Report, or PEAR, is to identify potential environmental impacts the project could have. This is done to both identify potential delays to the project as well as identify topics to be researched later on. For this project no significant environmental impacts were identified.
Geometric Approval Drawing
The Geometric Approval Drawings, or GAD, is a design document meant to show off the various geometric features of the project. In addition the document also shows the traffic analysis reports for the project if there are any. Two GADs were generated for this project: one for the Partial Cloverleaf Interchange and one for the Diverging Diamond Interchange.

Advance Planning Study
The purpose of the Advanced Planning Study, or APS, is to design any significant structures of the project in order to plan and provide accurate cost estimates. This project only has one significant structure, the bridge, and two APSs were designed for each alternative.
