Dec. 8 project update

Posted on Dec 8 2014 6:21 PM
WSDOT and Seattle Tunnel Partners are continuing to gather and analyze data to help us further assess ground settlement near the SR 99 tunnel access pit. This continued analysis will inform our understanding of whether the settlement has stopped, and the extent and location of the settlement. It will also inform decisions about dewatering activities near the pit. 
We are working with STP to develop a plan to safely stop dewatering if data shows continued settlement in this area. To stop dewatering, STP must develop a comprehensive plan to ensure the safety of workers and the public, as well as the surrounding buildings, utilities, the viaduct and the access pit. 
In the meantime, we continue to inspect buildings near the access pit and monitor the viaduct on a daily basis. Public safety remains our top priority, and we are taking every precaution to protect the public and infrastructure as this project moves forward.
We will continue to provide updates as we have them.
