A proposed "road diet" that would add a turn lane in the center of Nickerson Ave. NW, add a bike lane in one direction and a sharrow in the other, and reduce travel lanes for cars to two, has been postponed indefinitely. Seattle Department of Transportation (SDOT) traffic engineer Eric Widstrand says the agency "wanted to make sure we coordinated [the Nickerson rechannelization] with the Alaskan Way Viaduct" replacement. According to SDOT's web site, the agency needs to "evaluate how Nickerson Street would interact with the roadway network... taking into account the north portal of the bored tunnel" that is supposed to replace the Alaskan Way Viaduct, according to SDOT's web site. Translated, that means: SDOT is waiting to see if car traffic on Nickerson will go up if and when the bored tunnel is built. Although residents expressed opposition to the changes at community meetings held by SDOT last month, Widstrand says the decision was "not based on community concerns." Tomorrow is the last day to comment on the proposal.
