REINFORCED EARTH WALLS ON I-8ON NEAR GLENNS FERRY

The designated route for I-8ON in the section between East Hammett to Glenns Ferry, Idaho traverses two areas where the Snake River has cut a narrow passageway through the mesas that characterize the terrain. Since the route crosses the lower portion of an old slide, the consideration was to design so that the present stability would not be impaired. Erosional characteristics and sedimentation production in open cuts and fill slopes were important concerns, particularly with the blow sands of the area. From the standpoint of roadway alignment, the problem was to accommodate an Interstate Highway and its frontage road between a rail mainline at the edge of the Snake River and an important irrigation canal on the steep sidehill above. Retaining walls then became a necessary feature of the design. This paper discusses the design of the retaining walls with regard to the foundation and the structure of the reinforced earth walls. The construction of the walls is described with emphasis on the cost, method and schedule of erection.
