Changes are taking effect that could impact the price of your commute.

Drivers, you might find yourself paying a little more for a drive along one of metro Atlanta's express lanes.

It used to be in existing express lanes the price depended on the time of day and traffic. The more congestion there was, the higher the price. Well, there is no longer a maximum price.

Before this change that goes into effect on Monday, commuters on I-85 knew the price for a 16-mile ride could not rise above $13.95. On I-75 in Henry County, the maximum was different at the max of 90-cents per mile.

That's all gone.

To make the pricing more uniform for existing and future toll lanes there is now a blanket minimum price.

During the day, 5 a.m. to midnight, the minimum price on all toll lanes is now 10-cents a mile. From midnight to 5 a.m., you'll pay a flat 50-cents per trip no matter how far you're going.

According to the toll authority, the I-85 toll lanes were hitting that maximum $13.95 price ceiling nearly every day during rush hour. Now, the authority is free to charge more during times when congestion is heavy.

The main impact will be on drivers who use the lanes for the entire length of the toll lanes. The authority said only a fraction of commuters actually do that.
