Phase 1: Corridor Planning (completed)
 Overview
Phase 1 gathered and examined existing information on the corridor in order to develop the Need and Purpose Statement, which defines and influences the rest of the project development, including the range of alternatives studied and, ultimately, the selected alternative. Phase 1 activites included:
-
Completed data gathering (i.e., traffic, mapping, environmental, roadway)
-
Assessed travel needs and existing conditions
-
Evaluated previously identified projects and studies
-
Examined existing conditions
-
Prepared Existing Conditions Report
-
Prepared Need and Purpose Statement
Project Need: Why is this project needed?
The following are highlights of the existing conditions along the corridor. They quickly illustrate why this project is being conducted.
Current Traffic Congestion: I-285’s top end is one of the most heavily traveled and most congested corridors in Georgia, serving between 200,000 and 250,000 vehicles per day.
Future Travel Demand: Based on anticipated residential and employment growth, travel demand in the corridor is expected to continue to grow.
Safety Concerns: The frequency of crashes along the corridor is higher (worse) than for other similar roadways throughout the state.
Future Growth: The population of the metropolitan Atlanta area is also expected to increase significantly from 2005 to 2030. Similarly, future growth of residential and higher-density developments along I-285 is both highly anticipated and desired.
System Linkages: The study corridor links the major interstates of I-85 and I-75 and all of the business and residential centers within the corridor limits. I-285 is the only east to west connection for these two major interstate corridors in the northern Atlanta area.
Transit System Linkages: Significant east to west travel patterns exist with high demand for east to west transit service; however, no transit facilities exist along the corridor.
