While the Centre has imposed an additional cess of 50 paise for the development of national highways, 34.16 per cent of the central road fund (CRF), amounting to Rs 1,600 crore allotted to states and union territories, still lie unspent. States have not come forward with enough proposals for road development.Delhi, despite being the national capital, sets a poor precedent. Of the total Rs 137 crore accruing to Delhi in the last 4 years, only 13.68 per cent (Rs 18.84 crore) was spent.No funds were released for 3 years, 2001-03 and 2004-05. Bihar and Kerela had accruals of Rs 132 crore with a utilisation of nearly 45 per cent.
