The Gurugram-Jaipur corridor of National Highway 48 (NH-48) is set to become a completely barrier-free system from August 1. The Multi Lane Free Flow (MLFF) toll system will start at the Shahjahanpur toll plaza in Rajasthan, allowing vehicles to pass without stopping to pay toll. Officials said Shahjahanpur was last toll plaza on 270-km Gurugram-Jaipur corridor without the MLFF system.
