TriMet fares are raising on September 1, along with increased trips on 10 bus lines and a new "rolling" 30-day pass.

Starting Thursday, adult All-Zone and 2-Zone single fares will go up a nickel to $2.40 and $2.10, respectively. The cost of an adult monthly pass will also jump by $4 to $92 and a youth monthly pass edges up a buck to $27. 

While the [new "rolling"] pass will be the same price as any other 30-Day pass, it will give riders the convenience of buying it at any time during the month, TriMet said. It's valid 30 days from the date of purchase. 

Currently, monthly passes are good only from the first day of the month through the last day of the month. They can be purchased only after the 20th until the start of the new month. The pass must be in hand by the first of the month.
