Toll lanes are being proposed for major highways throughout metro Atlanta including along Interstate 575 in Cherokee County.

The staff of the Georgia Department of Transportation on Wednesday proposed the state add toll lanes to stretches of several roads.

The proposals presented at a DOT work session in addition to I-575 include stretches of Interstate 285 and parts of I-20, Ga. 400 and northern I-75. An extension of Sugarloaf Parkway in Gwinnett County also is included.

The DOT 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 new plan would include optional, reversible toll lanes alongside I-75 and I-575 in Cherokee and Cobb counties.

This project, along with toll lanes on I-75 to I-20 at Thornton Road, could be put out to bid before the end of the fiscal year in June.

The cost of the toll to use the new lanes has not yet been determined.
