SR 104 - NE 195th St Gabion Rock Wall Emergency Repair - Complete October 2016


WSDOT built a new retaining wall at the intersection of SR 104/Ballinger Way Northeast and Northeast 195th Street in Lake Forest Park in October 2016. The previous rock wall, which was made up of rocks placed in large wire cages called gabions, had pulled away from the roadway embankment on the southeast corner of the intersection, leaving an exposed vertical dirt face along Northeast 195th Street.

After removing the gabions, contractor crews installed steel structural beams and steel sheets to create a new wall then backfilled it with gravel. Protruding through the wall is a culvert that carries Ballinger Creek under Northeast 195th Street. Had it been left unrepaired, the exposed dirt face would have eroded, eventually undermining the sidewalk and the southeast corner of the intersection.
