This gives some idea of the scale of the project. For organizational purposes the workforce was divided into seven categories: veterans 'engineering corps, infantrymen, military convicts, job training brigades, unemployed youth, public and privately owned enterprises, and, in summer, student volunteers from the China Youth Corps.
為了籌組如此龐大的人力，當年即有榮民工程總隊隊員、陸軍步兵、軍事監犯、職訓總隊隊員、失業青年、公民營廠商以及暑期參與救國團活動之志願青年學生等七種人力來源，全數投入中橫公路的開發。
