SEATTLE (AP) - The Alaskan Way Viaduct has settled up to a quarter inch during the past month, but transportation officials say the waterfront structure is still safe.

The Washington State Department of Transportation said Friday that its bridge experts are confident the minor, uniform settlement between South Main Street and Railroad Avenue South does not pose any new safety risks to the public.

The viaduct is still vulnerable to earthquakes, but transportation officials say it’s safe for everyday use.

The city of Seattle announced last month that it was hiring its own consultant to determine if the viaduct has been undermined by the effort to replace it with a tunnel to carry Highway 99 traffic. Officials asked for the study because of previously reported settling.

State officials say the viaduct has been settling for years and probably will continue to do so until it is removed.
