Recent Progress
WSDOT and WDFW are planning a meeting with Rafter Groups. Yakima County issued the Shoreline Permit in December 2008. Washington Department of Fish and Wildlife submitted the draft Hydraulic Project Approval for comments to WSDOT in December 2008.
Design team work is approximately 90% complete. Construction is scheduled to begin in 2009.

Design Construction Impacts
The profile modifications to the alignment will possibly impact HQ Bridge from delivering a set of bridge plans for review in February 2009. This delay most likely will not impact the advertisement date set for April 2009.

Environmental Impacts / Compliance
Yakima County has officially recommended that WSDOT design the project to use the existing road and reduce the new floodplain fills as much as possible. Under the county’s Shoreline Master Plan they need to be assured that the project is minimizing impacts to land area that is useable for shoreline.

Impacts to Traffic
We plan to utilize existing bridges to detour traffic.
