Brian Collins and Kent Browning of the Technical Support Branch's Waterways Section, aboard the Huntington District's 26 ft. survey boat, plan their route to survey the navigation channel after the demolition of piers from the old Ironton-Russell Bridge. The bridge was demolished once it was replaced by the new Oakley Collins Memorial Bridge that opened in November 2016. Brian and Kent worked closely with the Ohio Department of Transportation and the U.S. Coast Guard's Huntington Marine Safety Unit to reopen the channel once the demolition was complete. Brian and Kent used the array of sophisticated sonar aboard the survey boat to make sure that no obstructions to navigation were present after detonation. Once they gave the "all clear" to the Coast Guard the channel was once again open for commercial traffic.
