The Illinois Tollway is expecting the busiest Labor Day weekend in its history, spurred in part by gas prices that are a dime lower than a year ago. The tollway could see seven-point-two-million drivers this weekend, a two-percent increase from last year. Drivers will find average gas prices of three-82-per-gallon around Chicago, three-61 near Champaign-Urbana and three-33-a-gallon near Springfield.
