I felt this shamal road is danger..because,
this road speed limit is 120Kmh and some places has 80Kmh, where the flay over work progressing.
normally people will slow down their vehicle except, regular drivers and they know well where is no radar or camera exist...these people continue drive in 120Kmh speed...
other will become in confuse..
so, i suggest there should have enough traffic control on these area..
