59N & 610W Ramp (northside)

Does anyone know why the ramp from 59N to 610W now merges to 1 lane, but only partially around the curve???? I didn't see any signage warning us of the change before it happened. I can't find anything online to know if it's temporary, and it makes my drive home more painful than it already was. TXDoT needs to work on their communication skills!!!!!
