Metro riders may be scratching their heads trying to figure out how much they will be expected to pay for their commutes under a new fare proposal that is expected to begin June 27.

The maximum fare would be $5.45 for Metrorail riders and $1.70 for bus, but what about shorter trips? It’s a complicated proposal that has many layers – different prices for peak times, even higher prices for “peak of the peak” times, surcharges on paper farecards and cash payments on buses — all on top of the already distance-based fare structure for rail trips.
