Project limits:  Lake Alice Road SE at 339th Ave SE
Project type:  Drainage / Culvert Improvement

Project description

Monitor condition of pipe, Place emergency response facilities, replace existing culvert.

Why is King County doing this project?

The 48 inch diameter culvert is severely deformed 35 feet below the surface of the road and a portion of the bottom of the pipe has rusted through. Complete collapse of the culvert or its plugging appears imminent. If that occurs the sole access road could become impassable.

Status as of November 25, 2015

Construction of the Lake Alice Road SE culvert replacement project began on Jun 22, 2015 and is scheduled to be completed on Aug 28, 2015. The work will require a full closure of the road at the project location. A detour route through the Snoqualmie Ridge community will be opened for public use during this construction.
