The Bonneville Power Administration has announced they plan to upgrade and put in a new 500 volt underground transmitting line from Eastern Washington's Grand Coulee Dam during 2012 and beginning as soon as February.During the construction the nearby highway and park may need to be closed for short periods of time but the dam's famous laser light show in the evening hours will not be interupted.The news of the project is great for jobs because the BPA estimates it will create dozens of construction jobs for a part of Washington that could use the good paying jobs.
