His argument is that if we remove the roundabouts, we are likely to make things worse than they already are.
Secondly, he is wondering the point of building the overpass while the by-passes are expected to do exactly the same function, i.e., remove transit traffic from the city centre.
Roundabouts take more time to get around than it would in a T junction. The speed and ease at which the car negotiates a roundabout is lower than a T junction. Take Uhuru Highway/Kenyatta Avenue roundabout. If you had cross junction, and you open both sides of Uhuru Highway for the straight moving traffic, compare that to the current situation. Where as in a cross junction traffic will flow straight and smoothly, with the roundabout, you have to negotiate a mini-round before proceeding straight.
The by-passes are taking all that traffic that would otherwise, not be passing thru' the CBD. Does that solve the traffic issues of the guy who lives in Embakasi and works from Kabete.
All the roads/by-passes/over-passes are needed.
