It doesn't need to have a barrier, as long as it has a central reservation, it's 70 unless the signs say otherwise. Same with 30 limits, if it has street lights and no signs to say otherwise, it's a 30mph zone.
As for the idea of lower limits by T junctions, that applies in some countries. In Poland the speed limit on a single carriageway is 90kph except for 200m either side of a T junction or pedestrian crossing where it drops to 60kph. So when you are clocked doing 99kph as you enter the 200m to a T junction zone, it costs you 100 Zloty (which at nearly 4 Zloty to the pound, I thought was quite a bargain, no points either!).
