The Port of Hood River has a lot of engineering work taking place on the Interstate Bridge at this time.  Core samples of the concrete piers to determine their condition, seismic analysis to determine points of vulnerability, a check of auxiliary truss connections, and an initial analysis of the impact of overweight trucks on the bridge have either just taken place or are on-going.  Port Executive Director Michael McElwee added there is some state legislation pending that could be helpful.  Repairs to the auxiliary truss connections are slated to take place in the next fiscal year, while the analysis on the impact of overweight trucks on the bridge is to be presented to the Port Commission at their next meeting.
