Finally the time has come for CityVille's first expansion ... across the river. Zynga finally released a new building of sorts to the game today, the Bridge. (However, what we all hoped was going to be a trip to the beach turns out to be just more green space to expand on.) Once you've reached 5 thousand population or higher, you will receive a new Goal upon entering the game titled "Over the River." And it has just one requirement: Place Bridge. It gets even better: if you've yet to expand to to the edge of the river, placing the Bridge will expand your city to that point for free. And yes, it gets even better than that, as you'll receive a free expansion once you reach the other side of the river, too. However, you're gonna' have to work for it.
