The Georgia Department of Transportation plans to hold open house meetings on a project that would bring high occupancy toll lanes closer to Hall County. Meetings are set for Sept. 29 in Duluth and Oct. 2 in Braselton on plans to extend the HOT lane system, also known as Express Lanes, up Interstate 85 in Gwinnett County from Old Peachtree Road to Hamilton Mill Road. Unlike the existing HOT lanes on I-85, the new Express Lanes would involve building new lanes, rather than converting existing high occupancy vehicle lanes.
