I have creeping phlox on both sides of a walkway. The one side looks great leaves are green and the other is yellow and brown. Any idea what could be causing this? It should stay green all year long.

One side gets more sun than the other? Or the ground slopes and not enough water for the plant? Something to do with water I'd guess - unless you've treated the walkway with weedkiller and it slopes in the direction of the sick phlox, so that run off has damaged it.
