I was entering Georgetown via US 17 coming from Myrtle Beach. There a couple of bridges to cross: the first bridge is 60mph (US 17 is mostly 60mph).

As soon as you clear the bridge, it becomes 45mph going into the 2nd bridge. It then becomes 35mph at the base of the second bridge. Cops wait at both sides.

And yeah, watch out for the speed sign! It was positioned at the far right away from the bridge. You are lucky if you can see it from the left lane as you are going down the bridge.
