Downed power lines across U.S. 26 forced the closure of the highway in both directions Wednesday morning.

The closed section was between Interstate 405 and Sylvan.

As per KATU's reporters on the scene, the situation was precarious for drivers - pitch black, dense fog, and rain-slick roads.

Westbound U.S. 26 was closed at I-405, and eastbound U.S. 26 traffic had to exit at Sylvan.

At around 6:30 a.m. both lanes reopened.

Travelers were advised to plan for slow travels and find alternate routes during the closure.
