Chief Ministers of many states are on board with the decision, Gadkari told reporters on the sidelines of a programme here.
"We will sign support agreements with states for dredging of their rivers for Inland Waterways. NHAI contractors will do dredging and we will use sand in our road construction without cost. Excess sand will be used by states or auctioned. This will expedite highways construction," he said.
Gadkari said similar support agreements are being signed for expediting highways construction.
He further said that the Maharashtra government is preparing a detailed project report (DPR) for 7,000 kms while Jharkhand has been assigned the task to prepare DPR for 3,000 kms.
"Telangana is preparing DPR for 2,000 kms," he said.
While building roads, the Ministry is equally concerned and reports were likely soon how to bury heaps of garbage under roads to be constructed to get rid of the pollution problem, Gadkari said.
The government has taken a number of steps to reduce cost of construction and improve its quality including building of concrete roads for which 95 lakh tonne cement has already been booked for three years, Gadkari said.
