The National Trust for Historic Preservation has written an alarmed letter to the state department of transportation expressing concerns about WSDOT's plans to demolish the historic 619 Yesler building, home to more than 100 artists' apartments and studios, as well as the impact the deep-bore tunnel will have on the Pioneer Square neighborhood generally.

WSDOT, western National Trust director Anthea Hartig writes, has "refused to acknowledge that the loss of this building and other [tunnel] impacts would cause an adverse impact on... the [Pioneer Square-Skid Road National Historic] District as a whole."

The letter asks WSDOT to include the Trust in future decision-making about the viaduct replacement, which---given that the state has said it plans to tunnel under Pioneer Square no matter what the fate of the Western Building---seems a bit too little, too late.
