Under bridge near marston fields estate

The speed sign hasn't been working for around 6 months, I can see this problem was reported by some one else back in May, yet has not been fixed and has been left unworking. This is a road where young children walk to the local primary schools and nurserys and middle school aged children get picked up by the school bus. Majority of cars go over 50mph down here daily, it is a 30mph road, yet extremely dangerous as no one takes any notice of the signs. Fix this problem and look into other ways to make it safer for young children and adults.
