The 7.9 magnitude earthquake that hit Alaska Nov. 3 - one of the most powerful recorded in the United States in recent times - damaged six bridges, The Fairbanks Daily News Miner reported Dec. 10.

Two of the bridges were damaged to the point they must be replaced; four are in good enough shape to be repaired. All six are still stable enough to make it through the winter, The News Miner reported. State Department of Transportation engineers inspected more than 100 bridges on seven highways after the quake.

The two bridges that must be replaced - the Slana Slough and Mabel Creek bridges on the Tok Cutoff - are able to carry traffic, but could not withstand another shaking, officials said. The highway sits on top of the Denali Fault, which produced the quake.
