Pre-demolition activities at former MOHAI site postponed
On March 11, WSDOT crews began pre-demolition activities, including asbestos abatement and removal of interior materials of the former Museum of History & Industry (MOHAI) building.
On April 2, WSDOT decided to postpone further pre-demolition activities until WSDOT obtains ownership of both the MOHAI building and the property underneath it. WSDOT currently owns the building while the City of Seattle owns the property. Obtaining ownership of the property will provide WSDOT improved access and ensure public safety when we proceed with demolition activities in the future.

Crews are continuing to collect data from geotechnical monitoring wells in the Seattle area of the SR 520, I-5 to Medina: Bridge Replacement and HOV Project. These wells are part of an ongoing geotechnical study of soil and groundwater conditions. The information gathered helps us better understand the composition and characteristics of the ground in this area, which is vital to continuing structural engineering design and completing future SR 520 improvements in the area.
Update: Beginning April 15, WSDOT will perform geotechnical investigations in the Union Bay Natural Area (UBNA). Crews will be taking soil samples and installing monitoring well equipment in and around the parking area to study soil and groundwater conditions to prepare for future wetland mitigation work.
Monitoring well installation began April 15 and last approximately one week. The wells will be in place through summer 2014. Work will occur on weekdays between 7 a.m. and 6 p.m. The primary impact will be temporarily reduced parking (up to four spaces per well) in the lot southwest of the Center for Urban Horticulture during drilling and monitoring well installation.
