The government has also proposed to set aside a buffer area along the highway for industrial and allied activities and has already earmarked the first 300 km covering Valsad, Navsari, Surat and Bharuch districts. Out of the total length of 1,630km, a stretch of 140km will be developed as greenfield coastal area while the remaining 1,490km will be brownfield road. The corridor will be minimum ten metres wide with three driving lanes, while at present, the existing roads are less than five metres wide and a fixed area along the corridor will be declared as a buffer area and will be reserved for future development and will truly be a coastal highway corridor. The project is estimated to cost ₹2,400 crore and is slated for completion in three years.
