Free transit passes designed to help reduce air pollution were used for 28,500 trains and bus boardings between Feb. 17 and April 7.
The Utah Transit Authority related those results about the RideClear program it operated in the period with partners Zions Bank and the Utah Clean Air Partnership.
The UTA said it distributed 7,000 free weekly passes worth $50 each. They were offered at various times online, and disappeared quickly. UTA also staged numerous giveaways at stations, announced online on Facebook or Twitter.
