In brief

During colonial rule, British administrators implemented one of history's most ambitious infrastructure projects: a 4,000-kilometer customs barrier stretching across India. This defensive hedge system was designed to monopolize salt taxation and prevent merchants from circumventing high tariffs by smuggling salt from lower-taxed regions. The massive undertaking required extensive maintenance crews and substantial financial investment. Eventually, policy reforms and standardized taxation across territories rendered this monumental structure obsolete, marking a significant shift in colonial economic strategies.
