FHWA Improvement Type

The FHWA Improvement Type (IMPTYP) page stores information from the Federal Highway Administration (FHWA) about Improvement Types that should be used to properly record project information on various pages in Advantage. Because the FHWA occasionally phases out Improvement Type Codes, the status of each Improvement Type is captured by the Active, Effective From Date, and Effective To Date fields. However, these status fields are not used to enforce whether an Improvement Type is valid when creating or updating Program and Program Phase data since older Improvement Type may be used with ongoing projects established when the Improvement Type was valid.
