Casthorpe Bridge (64)- Take Care!!!

Caution should currently be taken when approaching and exiting (Grantham side) of Casthorpe Bridge (64) on the Grantham Canal towpath (NCN 15), the towpath although concrete covered near the bridge it is has experienced some subsidence resulting a deep edge to have appeared around a concrete pipe box and if caught wrong with your bicycle wheel could result in it guiding you towards the canal.
I have sent the Canal & River Trust photos and an email to report the problem and ask for them to look at rectifying the problem by re-concreting the towpath pad so it is flush with the limestone surface and concrete box.
