Screening Process

These alignments were combined into nine corridors. A screening process was conducted to identify HSGT alignments to advance into the Tier 1 EIS. The two-step process included an initial corridor screen to advance the best performing corridor(s) based on the criterion of transportation mobility and a second screen of alignments that provides a more detailed assessment relative to ridership, mobility, environmental, and financial/economic criteria. The process has resulted in the recommendation of the following four alignments for further analysis:

• I-75 Median Southern Crescent NS
• I-75 Median Southern Crescent
• I-75 Non-Median Southern Crescent NS
• I-75 Non-Median Southern Crescent
