East of Snoqualmie Pass in Washington in the northwest U.S., westbound Interstate 90 had a snow shed midway along the east shore of Keechelus Lake (, milepost 57.7); it was removed in 2014 in preparation for the construction of bridges to replace it. The concrete structure covered two lanes on a curve and was constructed in 1950 for U.S. Route 10, then one lane in each direction; it marked the first time precast construction was used for a highway structure in a mountainous area and was the last remaining snow shed on an Interstate highway.
