Do you want to be in the middle of the loop or tangent to the side of the loop? (And if re-paving obscures the layout of the loop, then you're SOL)
FWIW I stop at all red lights except for when the intersection is straight-ahead + left only, so that the bike lane is not in danger or in the way of any traffic. I'm also scrupulous with arterial stop signs, purely residential stop signs not so much.
