Could someone downlock this segment to L3 so that I can correct the layout of Fetter Lane
Many thanks.
You forgot to include any segments in your permalink. 
However, I presume you want to correct the geometry around the junction of Fetter Lane, A4 New Fetter Lane & Bream Buildings?
I’ve down-locked the relevant segments for you. Please let me know when you’re done.
Thanks, done now. (Got sidetracked at work all day - wasn’t expecting it to be busy!)
