GDOT says the average speed on I-75 northbound from I-285 to I-575 at afternoon rush hour’s peak was 40 mph in April – twice the speed from April 2018, before the new lanes opened. GDOT also says rush hour has been reduced by an hour in the morning and in the afternoon.
The lanes use what GDOT calls “dynamic pricing” – the worse the traffic, the higher the price to use the lanes. The idea is to raise the price enough to discourage some people from using the lanes and keep traffic moving. The average daily fare for traveling the full length of the lanes was $1.70.
