Studies

85 Study

The Georgia Department of Transportation (GDOT) and Gwinnett County are partnering to conduct a comprehensive corridor study along I-85 between I-285 and I-985. The study area is roughly 18 miles long and is primarily located within Gwinnett County, with a small portion in DeKalb County. The study will propose solutions for the corridor to reduce congestion, enhance traffic operations, and improve safety. Through collaboration with stakeholders and the public, a wide range of potential alternatives will be identified. These alternatives will be analyzed, and recommendations will be developed for implementation.

Please see the video for informational purposes along the 85 Corridor. However, the survey being referenced in the video has been closed as of February 29, 2020. If there are any comments, please email 85Study@dot.ga.gov.

Planning & Environmental Linkages (PEL)

The study is utilizing FHWA’s Planning and Environmental Linkages (PEL) framework to encourage transportation decision-makers to incorporate environmental considerations, community, and economic goals early in the transportation planning process. Decision-makers can then rely on more robust planning analysis, studies, and decisions throughout project development and during the environmental review processes of transportation projects. PEL aims to create a more unified decision-making process, resulting in less duplication of efforts and more informed project-level decisions.
