L4->L2 Bucks - new roundabout

Can these three segments please be downlocked to a L2, so I can put a new roundabout in at this junction? This is a large raised roundabout, rather than one painted on the road, so I’ll draw big enough!

Details can be found here.

Downlocked.

Thank you.

Hopefully all good to be reverted to the auto lock level. I have made the roundabout itself a Major Highway to match the main road that it forms the majority of.

Quite right, a roundabout always takes the status of the highest-status road connecting to it.
Lvl 4 locks restored.
