It was a busy 2017 for Orange County’s toll roads.

In the midst of increasing traffic and longer commute times, the Transportation Corridor Agencies recorded record-breaking numbers for the county’s four toll roads: State Routes 73, 133, 241 and 261.

The four toll roads comprise 20 percent of Orange County’s highway system.

More trips were taken on the roads than during any other year in TCA’s 30-year history, said Sarah King, media relations manager for the tolling agency that manages the 51 miles of toll roads in the county.

More than 300,000 daily commuters and visitors used the tollways last year, resulting in more than 100 million tolls taken and more than $312 million in revenue, according to the TCA’s annual report.

The agency has 1 million-plus open tolling accounts consisting of FastTrak, which collects payments each time a transponder is read by a toll, and Express Accounts that are charged based on license plate readings at each tolling point.

Toll rates range from $2.77 for a trip from Rancho Santa Margarita to the Irvine Spectrum on the 133 and 241 freeways to $7.76 from San Juan Capistrano to John Wayne Airport via Route 73.

Ridership on the tollways has increased 20 percent in the past three years.
