Title	Another Photo Of Button Hole Bend
Subject	Photography; Landscapes and scenery; Transportation; Railroads; Alabama; Huntsville, Monte Sano; 19th century
Description	This photo looks down over the “Button Hole”. From outside the curve, one may see how the roadbed doubles back through a reverse loop after spanning two trestles over the creek hollow. Constructing a railroad up a mountain requires some careful planning and field surveying. Before construction work ever begins, the lead project engineer and his crew have to actually go out and walk the site to see what they will be dealing with. Next, a more detailed and preliminary field survey is conducted with a set of topographic engineering line drawings being prepared. With this, engineers can better calculate the best route to build the line with the least amount of cost. Other factors that are considered include right-of-way acquisition costs, social and economic points of interest, and environmental impact assessments.
