Until 1:30p.m. yesterday, the tower at Coast Guard LORAN Station Port Clarence was the largest structure in the state of Alaska and the largest LORAN tower in the United States. That was until the Coast Guard’s Civil Engineering Unit from Juneau and Controlled Demolition, Inc. conducted a demolition of the 1,350-foot Long Range Aids to Navigation tower. The tower stopped transmitting its signal on February 8, 2010 when LORAN-C was taken offline and was deteriorating to the point of posing a risk of an uncontrolled collapse.
