The proposals presented at a DOT work session on Wednesday include stretches of Interstate 285 and parts of I-20, Ga. 400, northern I-75 and I-575. An extension of Sugarloaf Parkway in Gwinnett County is also included.
The state announced this week that it was abandoning its partnership with the developer that originally proposed the I-75/I-575 project.
DOT officials say a new law reorganizing transportation planning made that change necessary and that putting the project up for bidding would produce the best possible project.
The Atlanta Journal-Constitution reported Monday that plans would include optional toll lanes alongside I-75 and I-575 in Cobb and Cherokee counties.
