Inspection results show no additional settlement of the Alaskan Way Viaduct between Columbia Street and Yesler Way, and no new structural damage.

"It's always good news when we do not see additional settlement, but we still need to move forward with the repair to keep the viaduct safe for drivers," said Harvey Coffman with the Washington State Department of Transportation bridge preservation office.

Since the 2001 Nisqually earthquake, the viaduct has settled approximately 5 inches between Columbia Street and Yesler Way. Due to the trend of continued settlement, the transportation agency started repairs this week to strengthen four column footings in this one-block area. Repairs involve drilling 88 steel rods surrounded by concrete, called micropiles, around the four existing footings. The reinforcements will make a wider and stronger column foundation, limiting further settlement into the fill soil.

The repair work, estimated to cost $5 million, will take about six months to complete. No lane closures on the viaduct will be required. About 20 parking stalls will be temporarily closed along with the traveling lane under the viaduct between Columbia Street and Yesler Way.

No work will take place between Nov. 22 and Jan. 1 to accommodate holiday travel and shopping.
