Little Pilchuck Creek Bridge No. 571 on 75th St NE
Description Completed Aug 2014 The approaches to Little Pilchuck Creek Bridge 571 needed to be repaired. The crumbling slurry blocks and rotten wing-wall piles at each corner of the bridge were replaced with concrete blocks and soil-wrapped walls. The soil-wrapped walls consist of one-foot layers of top-soil, hydro-seed and various geofabrics. The blocks protect the geofabric from ultraviolet rays and reinforce both ends of the bridge and the wing walls. Soil wrapping is a newer technique used to add stability and erosion control to the embankments and the bridge abutments. The approaches have been repaved to complete the work.
