Drivers taking the new I-595 express lanes will start paying tolls today.

Driving on the express lanes was free of charge since they opened March 26.

Fortunately, tolls will stay at the minimum 50 cents for the next couple weeks as officials continue testing the tolling equipment.

Eventually, variable tolling will take effect depending on traffic. Driving on the express lanes during rush hour could cost drivers up to $2 per trip.

The reversible express lanes travel eastbound between 4 AM and 1PM and westbound between 2 PM and 2 AM. The express lanes will normally remain eastbound on weekends.

Drivers must have a SunPass to access the 595 express lanes. Cash transactions and toll-by-plate are not available.
