The National Highways and Infrastructure Development Corporation Ltd will improve and widen a section of National Highway No. 127B into two lanes with paved shoulders from Darugiri to Williamnagar junction over a distance of 36.635 km. The work is proposed on an Engineering, Procurement, Construction mode and the decision to proceed followed deliberations with state and central forest officials. Compensatory afforestation is planned on 34.8877 hectares of non-forest land in Dagal Bolmedangh village under Dambo Rongjeng Block.
State authorities conveyed that the road is intended to shorten travel time for people travelling from Shillong to Williamnagar by avoiding a circuitous route through Guwahati, and that it is expected to boost tourism, support local industry and assist quicker transport of agricultural produce. Officials indicated that the project will provide wider developmental opportunities for the region while mitigation measures and compensatory planting will be used to address forest loss. Project execution and monitoring will be overseen jointly by the highways agency and forest department teams.
