Design Construction Impacts

The current managing group of a non-functioning railroad crossing is in disagree with WSDOT on the need to reinstall the crossing during construction.  WSDOT has agreed to reinstall the crossing at which time the track is used for rail traffic again.

Environmental Impacts / Compliance

The project will be a SEPA - Determination of Non-Significance.  The project will treat new stormwater runoff onsite as a result of new roadway constructed. 

Impacts to Traffic
This project will require the eastbound off and the westbound on ramps to be closed one weekend to install a City of Yakima Sewer crossing.  Reconstruction of the intersection will require a single lane closure.  Construction of the westbound on ramp will require a lane closure on US 12 at times.  Intersection closures will cause back-ups during high traffic flows.
