Design Construction Impacts
The construction of this project has been advanced by a year utilizing a design-build procurement method. Construction is anticipated to begin in mid-October 2008 and be substantially complete by June 2010. The WSDOT will take on the risk for administering the QA/QC for the First and Atlantic stage of construction.

Impacts to Traffic
The Construction schedule is compressed and the work is sequenced to minimize traffic and pedestrian impacts as well as major events at the adjacent facilities. Traffic will be mitigated through performing construction in the 1st Avenue/Atlantic Street intersection under a single contract that will combine the scopes of both the SR 519 and Alaskan Way Viaduct -Holgate to King project. MOT Task Force is attended by stakeholders and tracks any and all traffic impacts.
