By agreement with the scientific personnel involved, no cables were laid on the seaward side of the causeway in order to permit an earlier start on the curbing. Stiteen inch wide by 5Q-foot long sheets of flat piling left over from the Hawaiian Dredging Company operation were used as the curb. Threaded together to make a sheet 32” wide, they were set 121 apart and tied beck to the causeway walls by welding to scrap 6“ angles and reinforcing steel. The road was surfaced with local coral rock and sand. Stabilizationwas required around the Gamma Stations and along the lines of sight to eliminate interference from dust. The areas immediately adjacent to Gamma Stations A and B were stabilizedwith soil.cement, and the area around @mna C was covered with coarse sand. In addition, a sand strip 100’ wide was laid from tk stabilizedarea at Gamma A to the 400~ station and from the stabilizedarea at Gamma B to the AomonBiijiri lagoon. The 5 to 8 ton roller and the disc harrow used for the soil cement work could not be used in the soft sandy areas because the roller dug itself in, and the harrow penetrated too deeply. In these areas, mixing was done by hand and the soil cement was rolled by truck. In addition to the above conetnction, during the period of 1 March to 6 April, assistance was given to the various AEC technical groups in eetting up their installations. This assistance consisted of interior wiring, ditching for cables, laying come cables, erecting tent workshops, unloading nmterial, providing covered storage space, and furnishing small crews to work directly with the scientists and technicians.
