6 . Having gone through the pleadings of the parties, the report of the Court Commissioner Shri Devi Lal Vyas and the site plan and DPRs placed on record, we find that widening of the highway in question had been carried out strictly in accordance with the National Highway Rules and the IRC Guidelines, 2014. While finally arguing the matter, Shri Aidan Choudhary, learned counsel representing the petitioners, only limited his arguments to the non-construction of the slip lanes at certain portions of the roads, however, Shri Sunil Joshi, Advocate representing the NHAI, submitted that the requirement of constructing the slip lanes is governed by the flow of the traffic. As per Shri Joshi, after taking the complete traffic senses figures, the slip lanes had been constructed in the urban areas adjoining the section of the highway. The area of the road, which was referred to by the petitioners’ counsel alleging that the slip lanes have not been constructed, is beyond the sanctioning stretch of the highways and in the rural area where there is no requirement of constructing the slip lanes. Despite that, the NHAI officials had taken all the safety measures.
