A mudslide is covering one road near Snoqualmie and a washout has closed an intersection of two roads in Maple Valley.
The mudslide closure, in the 7100 block of 396th Drive SE near Snoqualmie, is expected to be cleared sometime Thursday.
But the washout, near the intersection of Maxwell Road SE and SE Lake Francis Road near Maple Valley, will take much longer to repair due to the extent of the damage, officials say.
The road there is collapsing under its own weight as water continues to eat at the soil below and rain saturates the ground.
One of the big problems at the washout site is the large amount of sand in the soil, which is more easily washed away than other types of soil.
King County roads spokesman Terry Depriest says the agency doesn't know how long it will take to repair the washout. Engineers will be on site Thursday to inspect the problem.
The overnight closures came after three others earlier in the week, including a mudslide over West Valley Highway South a quarter mile south of Ellingson Road in the town of Pacific.
