I have received this response from Network Rail about the poor condition of the railway pedestrian bridge between Lyon Park Avenue and London Road:
Work Request - Bridge Improvement Required - Bridge ID: LEC1/32 - Between London Road & Lyon Park Avenue, HA0 4DX
Thank you for contacting us about the footbridge going over the mainline near Lyon Park Avenue.
I have raised this with the structures team and they have let me know that this bridge is due for inspection later in the year, and they will take necessary action following the examination.
