Step 1 (Weight: 5)

Description: Review survey and mapping files


Step 2 (Weight: 15)

Description: Develop typical sections for each alternative

Step 3 (Weight: 80)

Description: Develop roadway geometric design.  Develop roadway geometric design for each of the following that apply:

  • preliminary cross-sections
  • proposed widening
  • preliminary wall locations
  • construction and clearing limits
  • major drainage work areas
  • provide preliminary TS&L line and grade to Structures.
