SNAILBACK WALL - FIRST FABRIC WALL REVISITED AT 25-YEAR MILESTONE

The successful performance of a 3-m-high geotextile retaining wall, the Snailback wall, is reviewed 25 years after construction. This historic wall, constructed in 1974 on a forest road in southwestern Oregon, is the first geosynthetic wall built in North America. It is located on the Siskiyou National Forest near Cave Junction, Oregon. Built of geotextile and earth materials, the wall established precedents for design and construction methods developed by the U.S. Forest Service and others. The paper reviews the design, construction, and performance of the wall, and compares and contrasts the groundbreaking methodologies used in 1974 with modern practice. Practical lessons learned from this historic wall are summarized in the paper. Today, the wall stands without visible degradation and, after 25 years, continues to support the Illinois River Road and its traffic. Like the wall, the basic design concepts still serve.
