Support columns almost completed
A section of the Alaskan Way Viaduct continues to sink, but state crews have almost completed work to stop it.
Bents 93 and 94, the pairs of columns and their cross braces between Columbia and Yesler streets, sank another 3/8 inch, bringing the total misalignment to about 5 1/2 inches. The most recent measurements were taken during the semi-annual inspection of the viaduct March 22 and 23.
At 6 inches, engineers with the Washington State Department of Transportation said repairs would be required.
