Construction of road fly-overs in city centre will ease traffic congestion

Increase in traffic congestion has become a serious concern in Kampala. As Uganda grows economically, there is need to improve infrastructure. However, improvement has to start with Kampala city which is the most congested and lacks proper roads, planned buildings, proper drainage and sanitation.
In order to ease transportation in Kampala, the Kampala Capital City Authority should take up the initiative of constructing fly-overs at major intersections.
As most of us are aware, fly-overs are an essential feature of road development initiatives in urban centres the world over. These are also resorted to extensively on the highways for ‘grade separation’, i.e. avoidance of crossings at the same level.
In developed countries, there are multi-level fly-overs to allow uninterrupted criss-cross movements through traffic in different lanes.
A fly-over is a bridge that carries one road or railway line above another either with or without subsidiary roads.
One type of fly-over which is used for traffic management at crossroads is the simple fly-over: In this case, the main road is used for fast moving traffic, which is made to pass by a bridge, providing ramps on both lanes; and the slow traffic is made to pass underneath.
There must be traffic lights at the intersection beneath the fly-over for proper traffic flow. At railway crossings, fly-overs are indispensable.
Fly-overs play a major role in stream Fly overs play a major role in streamlining the traffic control system. Plenty of time is saved avoiding congestion, and air, noise pollution , accidents , etc are reduced.
Fly-overs save motorists’ and commuters’ time as well as fuel and also contribute to beautification of the city. They also help create additional road space.
All roads and fly-overs are designed to accommodate the heaviest and tallest vehicle- the fully loaded truck- thus resulting in a gross over design for cars. The slab of a fly-over is designed to withstand the 20 tonne weight, (dynamic load) of a fully loaded truck. Feasibility studies be carried out by engaging urban planning experts.
However, proper location must be decided in constructing fly-overs. It should be seen that as far as possible the fly-overs purpose is consummated.
