Unlock to lvl 3 please 
It’s best if you say why you want a road unlocked, i.e. what you are trying to fix. Normally a road has been locked to a level reflecting it’s importance, and the high-level editor doing the unlocking ought to check the less experienced editors work and re-uplock.
However on this occasion you’re only asking for the road to be downlocked to the maximum lock level suggested by UK policy, so I’m happy just to unlock with no further info.
Sorry Ditchi,thank you for the unlock. I was responding to a UR.
