Abstract
The article is devoted to optimization of expenses for maintenance, major repairs, rebuilding operation and new construction during the life cycle of highway bridges. An approach is proposed for determining the necessary operational measures for highway bridges that are in the fifth operational state, based on the criteria for the effectiveness of operational interventions, without traditional long and costly procedures.
