The Port of Hood River Commission on Tuesday will hold the first of two public hearings on a proposed toll increase for the Hood River-White Salmon Interstate Bridge.  Under the proposal the cash toll for automobiles would go up from $1 to $2, while Breeze-By rates will go from 80 cents to $1.  Port Communications Specialist Genevieve Scholl points out it’s a similar structure to what the Port of Cascade Locks uses for the Bridge of the Gods.  She adds they are lowering the cost of Breeze-By transponders, which are now free for the first vehicle and $5 for each subsequent vehicle.  Scholl says they will also soon be launching an on-line portal for Breeze-By customers to manage their account.  The toll increase hearing will start at 5 p.m. Tuesday in the Port office in Port Marina Park.
