Broken fence between public footpath and M18 N/B exit slip

Broken fence separating a public footpath and the grass embankment to the M18 N/B exit slip. This is a wooden fence 2 panels are completely broken and there is now no barrier between the public footpath and the grass embankment. This is a busy public footpath popular with dog walkers and families. My concern is there is now nothing preventing a dog or a toddler gaining access to the grass embankment. The embankment is on a steep decline to the M18 north bound exit slip. My concern is that a dog or child can now easily access the M18 and be injured or cause an accident.
