• Abstract:
  This project aims to find the preferred alternative alignments for the Maryland section of existing US 220, using the highway ; alignment optimization (HAO) model. The model was used to explore alternative alignments within a 4,000 foot-wide buffer of ; the US 220 from I-68 near Lavale, Maryland to the West Virginia State line near McCoole, Maryland. It analyzed various ; alternative alignments within the project limit at a planning level of detail, evaluated them based on important decision criteria, ; and eventually found the best alternative alignments. Geographical and environmental issues as well as roadway geometric ; specification are also considered in finding cost-effective alternatives of the US 220. Five major agency costs (i.e., lengthdependent, ; right-of-way, earthwork, bridge, and maintenance costs) are considered as the decision criterion for optimizing ; alignments. The project was divided into eight sections based on environmental and geographical issues. Among those eight ; sections, some were classified as the locations where widening of the existing US 220 was preferred (named Case 1 sections) ; and the others were classified as the locations where development of new bypasses was recommended (Case 2 sections).
