Officials with Gwinnett County, cities in Gwinnett and four Community Improvement Districts have submitted a list of potential transportation projects for inclusion on the metro Atlanta region’s project list for the Transportation Investment Act of 2010.

The group of officials worked together to create the list, which came from the county’s Comprehensive Transportation Plan (CTP), corridor studies and other approved studies.

The three-page list of projects includes four light-rail proposals with an estimated cost of more than $937 million.
