A blue overhead sign suspended over the motorway from a post on the left, with a diagonal arrow pointing up and left, and the following text.
A629 [Hollow square diversion symbol] ; Rotherham (N).
Junction number: 35.
This is the last of a continuous run of five junctions over the last 12 miles that have all been signposted for Rotherham, which feels a bit excessive. I mean, it's a decent sized place, but it's not that big.
