The Port of Hood River will stop selling Interstate Bridge toll ticket books at the first of the year in preparation for transition to a new tolling system.   The Port will stop selling bridge tickets on January 1, but will continue to accept tickets for toll payment at the toll booth until the new system is operational, expected to occur in summer of 2016.  Unused tickets can be tendered at the Port office for a refund or credit toward a BreezeBy electronic tolling account.  Port officials say pre-sold tickets for bridge tolls are being phased out across the country as electronic tolling is becoming standard, and new system upgrades will not support ticket sales.  About 18 percent of bridge tolls are currently paid via the pre-paid tickets.
