Review: No further settling of viaduct

The latest inspection of Seattle's Alaskan Way Viaduct shows no further settling or structural damage.

State Transportation Department crews closed the roadway during a weekend last month to measure existing cracks and settlement.

Workers also performed some routine maintenance by removing loose concrete, repairing expansion joints and covering exposed rebar.

In April 2008, workers strengthened four support column foundations because they had settled approximately 5½ inches since the 2001 Nisqually earthquake.

DOT crews conduct inspections every three months to monitor the viaduct’s condition.

Workers this summer will begin replacing the viaduct between South Holgate and South King streets with a new side-by-side roadway that has wider lanes and meets earthquake standards.
