Pay-To-Drive Tollway HOV Lanes Approved

The Illinois Toll Highway Authority board today approved a plan for high-occupancy toll lanes, known as HOT Lanes or Green Lanes.

The plan is to install the lanes on much of the 80 miles of Chicago-area tollways where traffic is heaviest. Conversion will begin in 2010.

One lane on each of the four Chicago-area tollways would be reserved for buses and ride-sharers, who would pay the normal toll. Drivers of fuel-efficient vehicles like hybrids or others deemed "environmentally friendly" could use the lane if they pay an extra charge.

Motorists who drive alone also could use the HOT (high-occupancy toll) Lane at a premium rate, depending on congestion.
