I am expecting that this shoulde doable by modding, and who knows, maybe already implemented in the game but still:
worker's should gain also gain new attributes when they have built a lot of roads or so, like: bonuses per general speed, bonuses to roadbuilding speed, minebuilding speed and irrigationspeed. Last three might add too much micromanagement, but even if implementing just general speed, this way you might be able to get away without the usual worker hordes of 100 and so on.
