I-77 Express features dynamic pricing, which varies toll rates in real-time based upon traffic demand through a design to move traffic through the corridor at an average minimum speed of 48 mph or faster.
11 Toll Segments
I-77 Express is comprised of 11 toll segments:
Once you enter a toll segment, you are charged for that segment. If you decide to continue driving into the next toll segment, you will see a pricing sign for the second segment, well in advance, to help you determine whether to continue your trip in that segment of the express lanes or to exit the express lanes. Similarly, if you continue driving in the express lanes, you will pay the toll price posted at the beginning of each additional segment you use.
Separate charges for each of the toll segments you use for a single one-way trip will then appear on your billing statement. For example, if you enter the southbound express lanes at Brawley School Road and exit at Sunset Road, you will incur three separate toll charges for each of the toll segments you entered.
The map below shows the last exits prior to a new toll segment.
