Two lanes of westbound I-90 reopened to traffic after the roadway was completely closed for hours Thursday morning.
A mudslide is once again blocking all lanes of westbound I-90 in Issaquah west of the Highpoint Way exit and east of Front Street.
State crews reopened the left lane of I-90 just before 7:30 a.m., but closed them again before 8 a.m.
Trees, rocks and mud came down from a hillside at about 4:45 a.m. Thursday, disabling as many as a dozen vehicles. No injuries were reported.
Debris was across all four of the westbound lanes.
Mud is a few inches in some places and a little deeper in others. Large rocks and one or two trees are across the road.
Staff from the Department of Ecology and a WSDOT engineer are still assessing the situation.
