DRPA chief executive John Matheussen says public hearings on possible toll increases will be held after a traffic study is completed.
It currently costs $3 to drive a passenger car westbound across the bridges. There's no toll for crossing the other way on the Benjamin Franklin, Walt Whitman, Betsy Ross and Commodore Barry bridges.
Matheussen says the traffic study will take 30 to 45 days, and public hearings and board approval make October a "reasonable" estimate for implementing higher tolls.
The DRPA says toll increases are needed to pay for bridge maintenance and upgrades of rail cars for the PATCO commuter rail line.
