Design Construction Impacts
WSDOT is working on an alternative alignment assessment to present to the county and other resource agencies.

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.
