On my way to Wakefield on Friday I discovered that the A1/A57 junction between Worksop and Retford is now open in it's new, grade separated form.

So on the way back last night I carefully orbited the roundabouts and got new traces and I've now provisionally rebuilt it in it's new form. We still need a trace for the southbound off slip from the A1 and the new northbound carriageway of the A1 (what I have put in is a guesstimate based on the new southbound carriageway that somebody had already captured).

Somebody also needs to work out what has happened to the B6420, which used to terminate on the A1 about where the southbound on slip now merges with it, so the B road has presumably been realigned, possibly to terminate on the eastern half of the new junction although I didn't notice a road coming in there.
