SR 18 reopened after mudslide closure at Issaquah-Hobart road

A mudslide Sunday caused the full closure of eastbound SR 18 Monday morning after the slide crept into both lanes of the highway.

Eastbound SR 18 reopened Monday afternoon at Issaquah-Hobart Road after a mudslide spilled onto the road.

Initially, only the right lane was closed west of the Tiger Mountain Summit starting Sunday afternoon. But a slide started to move into the left lane overnight, bringing trees down with it after a weekend of rain. That forced the closure of all eastbound lanes.

On Monday, crews worked to clear six to 12 trees, mud and debris from the left lane. The left lane reopened shortly before 4 p.m. The right lane remained closed as a precaution.

The westbound lanes were not affected.
