FHWA defines an inactive project obligation as a federal-aid project with no expenditure for a year. Projects must comply with federal laws ( ) and regulations ( ) governing the Federal-aid Highway Program. A project that is considered inactive is at risk of having its federal funding removed and reassigned to another project. A LG must bill in a consistent manner during the term of the project. The TxDOT Project Manager must provide consistent oversight of project progress and billing.
