GEOTECHNICAL CHALLENGES FOR THE SPIRIT LAKE MEMORIAL HIGHWAY, WASHINGTON
State Route 504, the Spirit Lake Memorial Highway, to the Mount St. Helens National Monument presented unique geotechnical challenges during investigation, design and construction. The over-riding factor was the variability of the geology along the alignment resulting from the steep topography and complex volcanic rock sequence. A detailed account is given of the investigation carried out by the Washington State Department of Transportation to characterise the alignment for the final design. The organisation of the geological investigation into 4 phases is described. Details are given of the classification of rock, excavatability of rock, slope stabilisation, source of new material and embankment design. For the covering abstract see IRRD 873033.
