signs ?

coming off the M602 to jn 11 M60 today when i noticed that the signs for the A57 over the motorway pointing to the A57 were all in blue shouldnt they be in green as its not a motorway ?

They should be in green once you get onto the 57. Leading up to it they’ll be blue

The A57 should have been in a green box inside a blue sign showing you the slip road with the green box at the top of the slip road, was it like that?

nope all blue was my colleague who noticed it as we were going to our new depot and she had over shot last time as it didnt stand out .

All motorway signs are in blue even when the road off the motorway is not a motorway, just like you have said.
It was changed in 2010 going by the newest booklet “know your traffic signs”.
I did a google map search of said junction and seen it so I had to go and find out why.

I hope that has answered you question.
