It's too risky to install a safety fence on the M5 near Clevedon where a man fell to his death nearly six years ago.

42 year old Cecil Grant was killed when he stepped over the barrier between junctions 19 and 20 to repair a CCTV camera - and the coroner at his inquest has called for a new fence to be put up to prevent a repeat.

But the Highways Agency says the risks to workers of doing so and maintaining it outweigh the benefits.

However, they say warning signs have been put up.
