County Highway Systems - Project Development is the official record keeper of the primary "County Highway System" as specified in SDCL 31-12-2. Roads can be added or deleted from this designated system, but must follow these "procedures."

Federal Aid - Functional Classification determines the federal-aid eligibility of roads. However, a few roads that were eligible under the previously designated "federal-aid system" are also eligible.

Functional Classification - Project Development is responsible for coordinating the functional classification for all roads in South Dakota. Functional classification describes the type of service each particular road provides the traveling public.

Metropolitan Planning Organization (MPO) - Metropolitan Planning Organization (MPO) Coordination and planning coordinates between SDDOT and the three active MPOs in South Dakota by representing the Department on various MPO committees and providing technical assistance as requested.
