There will be intermittent closures of the Port of Hood River Interstate Bridge this (Tuesday) afternoon to accommodate surveys and inspections of the bridge’s lift span. The Port announced this morning that bridge users should expect up to 20 minute delays between 12:30 and 4:00 this afternoon. The inspections are to assess possible damage resulting from a suspected barge collision with the north lift span pier that occurred earlier this month. The Port indicated favorable weather conditions today are expected to change tomorrow…and the work must be performed during daylight hours. The bridge has been determined to be safe for vehicle crossings…but these inspections are to determine the safety of lifting the bridge’s lift span for marine vessels on the Columbia River.
