    Abstract: Methods, systems, and techniques for determining the vertical alignment of an infrastructure corridor having a certain horizontal alignment involve using a processor to model the cost of constructing the infrastructure corridor as a function of cost variables that vary with the vertical alignment of the infrastructure corridor. The processor looks up the cost variables at vertical offsets corresponding to certain vertical alignments of the infrastructure corridor and determines the cost of constructing the length of road at elevations located between pairs of the vertical offsets by interpolating from the cost variables at the vertical offsets; the interpolation may be linear. The processor determines, subject to infrastructure corridor design constraints, the vertical alignment of the infrastructure corridor from the cost of constructing the infrastructure corridor at the vertical offsets.
