Pending for 2026: System-wide Low-Income Discount Program

The Commission has directed the development of a low-income tolling program where qualifying drivers could receive a toll discount. The program will be developed over the next year, with targeted implementation in late 2026.

Low-income discounts will be phased in, starting with new tolled facilities, specifically the SR 509 & SR 167 Expressways. Offering low-income discounts on existing tolled facilities will be looked at in the future as the Commission considers future toll adjustments on them.
