The Guinness World Record for the world's longest road built with processed steel slag aggregates was set at which place?
- A.Angul, Odisha
- B.Raigarh, Chhattisgarh
- C.Hazira, Gujarat
- D.Bhilai, Chhattisgarh
Correct answer
Explanation
The correct answer is Raigarh, Chhattisgarh. The record road runs 1.85 km and was pursued jointly by the CSIR-Central Road Research Institute of New Delhi and Jindal Steel Limited, with the record conferred at an event addressed by Dr Jitendra Singh. Option A, Angul in Odisha, is a genuine part of the story but belongs to the next stage: CSIR-CRRI has received a work order for a 40-km road in Odisha from the Jindal Steel plant there, which is meant to take the technology well beyond the present record. Option C, Hazira in Gujarat, is where the technology was first demonstrated on a six-lane road to the port, and a 1.1-km slag road was later laid inside Hazira Port itself, but neither is the record stretch. Option D, Bhilai, is a well-known steel town used here only as a distractor. Keep the record with Raigarh and the future project with Angul.
