The Port of Hood River is embarking on a traffic analysis of the Waterfront area.  Port commissioners has approved a contract with an engineering firm to do the work.  Port Executive Director Michael McElwee says they want to know how traffic has changed since development in the area began in earnest in the past decade.  In 2011, the Oregon Department of Transportation did an interchange access management plan that set limits on how much traffic could increase from the waterfront and the Interstate 84 exit 63 interchange at the entrance to the area without some improvements.  McElwee says the Port board wants to know where they stand right now relative to those limits.
