Project Development and Design Manual (PDDM)
This Manual has been developed to provide information and guidance to engineering staffs involved with project development and design of highways. It will identify those standards, specifications, guides and references approved for use in carrying out the highway and bridge design responsibilities in the Federal Lands Highway (FLH) Program.
