PORTLAND, Ore. -- A Portlander will hop on a MAX train or TriMet bus on Wednesday and unknowingly break an all-time record for the city’s mass transit agency.

TriMet was expecting its 100 millionth rider in the last 12 months on Wednesday.

The agency said this marks the first time it’s surpassed the 100 million mark.

Many TriMet riders may benefit, too, with a free pass on Wednesday.

Transit officials said they’d be handing out free items and free all-day passes to celebrate the milestone.

One hundred free passes were handed out on Pioneer Courthouse Square after 6 a.mm.

Ridership has been on the rise for the last 20 years.
