Continuing previous work (Nelson, 1973) the author made a number of seismic refraction traverses over proposed road cuttings on the South Eastern freeway. Most cuttings should require blasting in parts to loosen rock material. However, where extensive weathering has occurred (as indicated by low seismic velocities) most of the material should be rippable. This is particularly so over the low rounded hills lying in the Bremer River valley.
