Miami Herald reports that MDX toll revenue increased by $105 million (82 percent) in just 24 months. A fiscal year financial report released late last week by the Miami-Dade Expressway Authority “shows its system of five highways generated $235 million in toll revenue in the 12 months that ended July 1. That’s up 28 percent from 2015, when MDX expanded tolling to all of its exits on the Dolphin and Airport expressways.” In a statement to the newspaper, MDX’s Mario Diaz pointed out that the controversial “closing of the system” in late 2014 was accompanied by toll rate decreases that reduced expenses for many motorists. “Those who paid nothing are now paying something,” Diaz said. Another financial report highlight, the newspaper notes, is that MDX “enjoys a much stronger financial position than it did a few years ago. In 2014, it had about $12 of debt for every dollar of yearly operating revenue. . . . In 2016, MDX had $6.74 of debt for every dollar of operating revenue” even though its debt level ($1.6 billion) was constant.
