I have suspicion they wanna make those non-free/put up additional guantries tho as I've seen them count traffic in the mornings along alt routes and then the other day they deployed traffic meters all the way to & the including on ramp o the highway![]()
I also noticed a few temporary traffic counters deployed on the old JHB/PTA road this week.
Maybe they're trying to calculate how much strain the e-tolling is putting on the back roads.
