The US city of Chicago is planning to introduce congestion pricing on fast lanes during rush hours to generate revenue and alleviate traffic congestion.

Motorists would pay anywhere between $2.19 to $5.39 to use the fast lane, according to a study conducted by The Illinois Tollway and the Metropolitan Planning Council.

The study also said that drivers could benefit if fast lanes or high-occupancy toll lanes were installed on the Kennedy Reversible Lanes, a section of the Jane Adams Tollway and the Stevenson Expressway.

Traffic congestion on Chicago expressways is third highest in the US, with the region losing an estimated $7.3bn a year in wasted time, fuel and environmental damage, according to Fox Chicago News.
