# M1 Sheffield LIVE: Major Collision Leads to Severe Delays with Air Ambulance Responding

A serious collision on the M1 southbound has resulted in significant traffic delays, prompting authorities to call an air ambulance to the scene. The incident occurred between junctions 33 and 32, impacting traffic flow from the A630 in Catcliffe, which serves the Sheffield and Rotherham areas, to the M18 interchange.

The crash has led to the complete closure of the southbound carriageway, creating long queues for motorists. There are additional delays due to a separate breakdown incident, affecting one lane between junction 34 at Tinsley Viaduct and junction 33.

As drivers navigate around the accident site, heavy congestion continues to build, highlighting the urgent need for motorists to find alternative routes. "M1 Southbound closed, long delays due to accident from J33 A630 (Catcliffe / Sheffield / Rotherham) to J32 M18 (M18 interchange). One lane closed and queueing traffic due to broken down vehicle on M1 Southbound from J34 A631 Tinsley Viaduct (Meadowhall) to J33 A630 (Catcliffe / Sheffield / Rotherham)," according to our traffic partner Inrix.
