A1 has been 50mph from Washington to Blaydon since they made it three narrow lanes years ago, not just a result of current roadworks. From Blaydon north to Great Park (or the junction after, can't remember) it's 60mph, again following the improvements to three narrow lanes. All used to be 70mph before the improvements of course.

Interesting on the Coast Road tonight noticed its 30mph and 50mph simultaneously along quite a distance of it - not sure if they've removed roadworks and left the temp signs or are just about to start and have been quick putting the 30 signs out, but either way they havent cancelled the 50s so an abundance of conflicting speed limit signs right next to each other along there atm.
