ADVANCING SOIL ANCHOR CONSTRUCTIBILITY: GLENWOOD CANYON, COLORADO

Glenwood Canyon is a 20 km long, 600 m deep, narrow gorge carved by the Colorado River in Western Colorado. It is characterized by steep, colluvial slopes extending from the face of vertical cliffs. The COLORADO DEPARTMENT OF TRANSPORTATION (CDOT), their designers, and the builders of the Glenwood Canyon Project were challenged with creating a four lane, divided highway, and a 2.4 m wide recreation path through this terrain while minimizing environmental damage. The terraced roadway concept was developed, utilizing retaining walls and cantilevered roadway slabs. Soil anchor technology became an indispensable tool in providing necessary tieback and tiedown anchors for retaining wall structures. CDOT's experience with soil anchor construction spans the last ten years and included nearly 12,000 m of anchors, ranging from 8 to 25 m in length. Construction and administrative details of soil anchor projects are presented. Included are recommendations for future anchor work in difficult terrain.
