In 1950 Central Government identified some of the important and busy stretches of Inter-State road network as National Highways to be maintained by State P.W. Directorate under the fund provision of Ministry of Transport, presently renamed as Ministry of Road Transport and Highway under Government of India. Special Road Organization Wing was formed within P. W. (Roads) Directorate in early Sixties to look after the National Highway sectors along with other roads in the State. Coal Road Construction Circle was one of the important circles within Special Road Organization Wing for looking after National Highway No. 2 well known as Grand Trunk Road. In Seventies the Special Road Organization Wing was renamed as National Highway Wing specially to look after the National Highway Sector only and in Eighties all the National Highway within the State was handed over to the National Highway Wing for maintenance and further improvement. Initial construction activities for the dream project of Durgapur Expressway was taken up by the Development Corporation but was stood over for the time being. In 1985-86 the project again picked up its position in the priority sector and was sanctioned as World Bank Project. A separate wing named as Durgapur Expressway Wing was created. After completion of the project the DEW Wing had been entrusted to look after another NH Project named as Belghoria Expressway. In 1995 and 1998 two Project Implementation Units were formed within P. W. (Roads) Directorate to look after the projects of Four-Laning of National Highway No. 2 from Barrakar to Ranigunj with World Bank loan assistance and implementation of West Bengal State Road Project respectively. Road and Building Research Institute was set up under P. W.
