Construction camps were established every mile or so. Experienced rock workers and tons and tons of powder were brought in to force the way through fields of massive boulders and up the sheer granite walls of the Peak. Nearly a carload of high explosives were required for each mile of road. Finishing gangs with widetired Good Roads trucks followed in their wake to pack and smooth the surface. What sort of a road has this builder built? Not only has it been made double track all the way, but three and four machines may go abreast at many points. Wide pull-outs are provided at the more interesting points for rest and an uninterrupted

All the sharpest curves are 26 to 50 feet wide and super-elevated. Masonry parapet and curve guard rail walls are provided where needed. Staunch bridges of reinforced concrete of the ballasted deck type are located on tangents only, and may be seen 300 feet away. The minimum sight distance is 200 feet, except in two places where but 125 feet could be obtained. The average is 400 feet.
