M18 J1 — Blackspot analysis Rotherham & Hellaby

Recorded collisions · 26 combined incidents · On the M18 within 2 miles of J1

Wider area: counting every road within 3 miles — local streets, A-roads, everything — 645 collisions are on record, 19 of them fatal. That figure tracks how built-up the area is rather than the road, so it is context only and the score below does not use it.
