The Port of Hood River Commission held its final hearing on a proposed bridge toll increase this week.  Under the proposal the cash toll for automobiles crossing the Hood River-White Salmon Interstate Bridge would go up from $1 to $2, while Breeze-By rates will go from 80 cents to $1.  About a dozen people testified, many focusing on the impact of the rate increase on low-income residents of the area.  Port Executive Director Michael McElwee says staff will now go back through hearing comments and consider how some of the concerns can be addressed.  The staff recommendation on the toll increase has included a provision that all new net revenue derived from the increase be dedicated solely to the Port’s bridge repair and replacement fund.
