The New York City Department of Transportation (DOT) maintains a portfolio of 789 bridges within the five boroughs of the City of New York. Because funding from all levels of government is limited, DOT anticipates the need to make difficult decisions regarding the allocation of its resources. In an effort to inform this decision making process, DOT has begun a study to rank its bridges by benefit cost ratio (BCR). DOT’s emphasis is not on whether the projects show a benefit cost ratio of above or below 1.0 in an absolute sense, but on developing a consistent benefit cost methodology based on readily available data that can produce dependable and replicable rankings across hundreds of projects. This effort has required that DOT think creatively with regards to travel time savings, safety, and social benefits. It is DOT’s hope that by developing a proper BCR metric for our bridges, DOT can better inform decision makers regarding the relative importance and cost effectiveness of each of our infrastructure investments. DOT feels that the lessons learned in producing this analysis would be of great interest to other municipalities facing similarly difficult decisions regarding their aging infrastructure.
