SEATTLE – Initial results from last week’s inspection revealed that the Alaskan Way Viaduct has settled approximately 1/8 of an inch, where foundation strengthening work is taking place between Columbia Street and Yesler Way. No new structural damage was caused by the additional settlement.
"This settlement does not come as a huge surprise,” said Jugesh Kapur, WSDOT State Bridge Engineer. “The viaduct has been settling incrementally between Columbia Street and Yesler Way since 2002."
"This continuing settlement reinforces our decision to move ahead with stabilizing the columns in this area,” added Ron Paananen, Alaskan Way Viaduct Program Director.
This fall, WSDOT began repairs to strengthen the foundations of the four columns that are settling in this area. The columns have settled approximately five inches since the 2001 Nisqually earthquake. The foundation work is expected to be complete in April, limiting further settlement in this area and preventing damage to the structure. This work is one of six improvement projects planned to replace or repair more than half of the viaduct.
WSDOT crews conduct visual inspections every three months to monitor the viaduct’s condition and keep drivers safe. Full inspections and closures are every six months, with the next scheduled for March 22 and 23.
