WSDOT and crews conducted the first rock blast on I-90 Snoqualmie Pass on June 15, 2010 at approximately 8 p.m. From now until October, crews will blast and excavate one million tons of rock from the slopes adjacent to I-90 near the Lake Keechelus Snowshed (milepost 58) in order to widen the highway from four to six lanes.
That was a sweet blast.
