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.
