I was told that the road between Tennant Gill and Darnbrook farm is to be closed from today for six weeks. (Haven't checked online; this is just a quick early morning heads up.)

According to the NYCC website, the closure is from 6th November to 20th December for a cattle grid replacement.

It looks like the catle grid at Tennants Gill is being replaced and the High Voltage work is in Henside Lane, up from Langcliffe
