I'll always make polygon separate from the road.
One of the reasons is that we mark road only with it's centerline and 
not whole dimensions, shape and width.
And if we connect the polygon to that centerline we create false data.
Those fileds end at the certain distance from road centerline, 1m, 2m, 
5m,10m... and there is no reason to virtualy extend them and falsify the 
real world.
