IMPACTS OF THE BRIDGE ON THE ECONOMY
The new bridge will enhance tourism because of its picturesque location. There will also be knowledge transfer from foreign expertise to locals since the exchange of knowledge is ongoing.
It will also contribute to the country’s economic growth by promoting the economic development and integration of Uganda within the surrounding Central African countries and providing guarantees to people and trade movement on the Northern Corridor Route. (NCR)
The new Nile Bridge will ensure safety of the NCR transportation system by relieving traffic loading from the existing deteriorating Nalubaale bridge structure which was built in 1950.
The bridge will be the first of its kind in the region and will have a system and gadgets that will monitor the temperature, forces and stretches of the bridge cables.
