Criticism
A 2012 report prepared by the World Bank’s Institutional Integrity Unit alleged that fraudulent and corrupt practices were being followed by Indian contractors working on national highway projects funded by it, and sought a thorough investigation into the matter. The report also alleged that contractors paid bribes and gifts, including gold coins, to "influence the actions" of officials and consultants of the National Highways Authority of India. Local bodies and major road owners - including PWD and National Highways Authority of India - were criticized for depending on old technologies and outdated specifications for building and relaying roads.
In March 2010, Government of India issued a new list of numbered routes with rationalized and systematic numbering. The odd numbered routes are drawn horizontally, with numbers increasing from western to eastern parts of India. The even numbered routes are, similarly, drawn vertically going north to south, with numbers increasing from eastern to western parts of India.
