Abstract: Aspects of the present invention relate to path determination for transport system infrastructure paths. In embodiments, methods and systems are provided for identifying alternative paths and determining optimized transport system paths for projects. The methods and systems may involve providing a client-based application having a GUI that presents a plurality of constraints that relate to a project, a server-based application for calculating the costs of a plurality of potential paths for presenting a subset of paths with associated cost data, and determining optimized paths for at least one of a pipeline, a conveyor, a canal, a multipurpose utility pipe, and a telecommunication line.
