Changed any parts recently? Like the water pump?
If not, I'd say your lower radiator hose is collapsing at speed and restricting the flow. You should be able to rev the engine and have someone watch the hose and see it happen.

How about a stuc thermostat?
200 on hwy, 160 when not.
It should be around 195 if i remember correctly
