How much is the SKYWAY toll fee?

Excuse me, could you please clarify the current toll fee for using the SKYWAY? I'm interested in knowing the exact amount that needs to be paid for a trip on this highway, as I'm planning a journey and want to budget accordingly. Is there a fixed rate or does it vary depending on certain factors such as the time of day or the type of vehicle? Additionally, are there any discounts or promotions available for frequent users or for certain types of vehicles? Thank you for your assistance.
