This pilot project tests more than 4,600 solar-powered Light-Emitting Diodes along a five mile stretch of I-90. The LED’s are installed along the shoulders, on the barriers and in the lanes from Denny Creek to the Snoqualmie Pass summit in both the eastbound and westbound lanes.
The LED's may reduce the risk of collisions in low light conditions on Snoqualmie Pass by 20 percent.
