Kampala Flyover Project, Uganda

Key facts:

Flyovers, Road widening/improvement, Pedestrian bridge, junction improvement (with NMT provisions), drainage design, relocation of utilities

Project Background

In order to mitigate traffic congestion within the Greater Kampala Metropolitan Area (GKMA) many projects and studies have been carried out. Among them, JICA conducted the Preparatory Survey on the Greater Kampala Roads Improvement Project in 2013 and 2014.

The Feasibility study concluded that the construction of two flyovers at Kitgum House and Clock Tower Junctions respectively, widening of Mukwano Road and improvements of interfacing roads and junctions would be effective and feasible to achieve the traffic congestion mitigation objective. The proposals of the Feasibility Study also considered improvement of traffic safety for non-motorized transportation (NMT).

Objective of the Project:

The objective of the Project was to mitigate traffic congestion and facilitate urban transportation in Kampala City, through construction of flyovers, road widening and improvement of junctions, thereby contributing to the sustainable economic and social development of Uganda, as well as vitalization of logistics and transport to neighbouring countries.

Scope of work:

The primary alignment of the Project commences at a point about 500 m to the south side of the Clock Tower Junction, passes through the Clock Tower Junction and along Mukwano Road to the Kitgum House Junction where it turns to the east onto Jinja Road which it follows to the end of the Project approximately 250 m east of the Africana Junction. Its total length is approximately 3.5km. Other ancillary components of the Project consist of

• A section of Entebbe Road between Clock Tower Junction and Shoprite Junction (approximately 200 m),
• Widening of Gaba Road at Nsambya Junction (approximately 500 m),
• A minor diversion at Kibuli Junction (approximately 100 m)
• A section of road between Kitgum House Roundabout and Garden City Roundabout (approximately 500 m), and
• A short section (approximately 120 m) of Nile Avenue leading from Garden City Junction.
