The board of the Metropolitan Transportation Authority voted on Wednesday to raise fares and tolls across its network of trains, buses, bridges and tunnels. On March 19, the base fare on subways and buses will remain $2.75, but riders will receive a lower bonus when buying a pay-per-ride MetroCard. Here is a look at what New Yorkers can expect:

How much will it cost to ride the subway?

The base fare will still be $2.75, but when you put at least $5.50 on a MetroCard, you will get only a 5 percent bonus. It used to be 11 percent. The bonus is a discount for people who do not buy an unlimited pass.

What about weekly and monthly passes?

A weekly MetroCard will increase by $1 to $32. A monthly pass will increase by $4.50 to $121.

Didn’t we just have a fare increase? Why are fares rising again?

The last fare increase was two years ago when the base fare rose to $2.75 from $2.50. Officials at the authority have said they must raise fares every two years to pay for the rising costs of providing service. State leaders agreed to regular increases as part of a financial rescue plan approved by the New York Legislature in 2009.

What about tolls at tunnels and bridges?

The E-ZPass toll at the Queens-Midtown Tunnel and the Robert F. Kennedy Bridge, for instance, will rise by 22 cents to $5.76. At the Verrazano-Narrows Bridge, where tolls are collected only when entering Staten Island, the E-ZPass toll will increase by 44 cents to $11.52, and the cash toll will increase by $1 to $17. Additional information about tolls on specific tunnels and bridges is available on the authority’s website.
