There's a pair of TIS/HARs at the Mackinac Bridge in Michigan. One of the bridge transmits at 530, the other end at 1610. Obviously not syncronized, but they are parallels. Also, from what I understand about synchronizers (and I heard this at my last amateur radio club meeting) they run about $20K for each site. But in mountainous areas, I can see where they are necessity.
