From the project page, looks like we could start to see the new lanes towards the end of August.
Construction to Start Week of July 26th
As part of its 2010 Arterial, Asphalt, and Concrete (AAC) program the City of Seattle Department of Transportation (SDOT), and its contractor Gary Merlino Construction, will be repaving a section of Nickerson Street in the lower Queen Anne neighborhood this summer. We will also be rechannelizing Nickerson Street to improve pedestrian and bicycle safety while accommodating traffic flows on this key arterial.
This project is primarily a pavement maintenance and traffic lane reconfiguration effort.
Tentative Construction Schedule
Construction work is scheduled to begin July 26th and continue into late August. Normal working hours will be between 7:00 a.m. to 4:00 p.m. Grinding off the top layer of asphalt and repaving of the roadway is expected to occur at night and is scheduled to take a total of 3 days during the first and second weeks in August.
The tentative sequence of work is as follows:
