Don’t think it turns to 40 until further up the road towards Marsden like. I got done by a mobile speed camera coming from Whitburn approaching the the gyspies green round about. I stick my cruise control on now cos it’s easy to go a few miles at 40mph & not drop to 30mph for the last stretch down the bank.The coast road in Shields is terrible for it. Always some twat doing 25 all the way from Gypsy's Green to Whitburn even though it's a nice wide clear 40mph road. Weird thing is, when they get to Whitburn and it changes to 30, half of them speed up and start doing 35!
