DYWIDAG Strand Tendons for Bridge over the Nile River in Uganda
In Jinja, the second largest city in Uganda and the second most important economic center in the country, a new stay cable bridge is being constructed across the Nile River. The bridge is a critical part of the Northern Corridor linking Kenya with the Democratic Republic of Congo and promoting trade in Eastern Africa.
The bridge, which is also known as the “Second Nile Bridge”, is the region’s first stay cable bridge and will first supplement and then replace the existing Nalubaale Bridge built in 1954 that is located 750m further downstream.
The new 4 lane hollow box girder structure is 525 m long and has a 135m long eastern span, a 290m long main span and a 100m long western span. The stay cables are arranged in a single plane and anchored in an approx. 80m high pylon in the shape of an inverted Y.
The bridge includes a total of 81 cross beams (2.5m deep, ranging from 400 to 700mm in width) that span transversely across the 22.9mwide box girder bridge deck. 72 cross beams accommodate the stay cable anchorages and are post-tensioned with a total of 72 Type 12-0.6" DYWIDAG Strand Tendons, 16 Type 19-0.6" DYWIDAG Strand Tendons, 236 Type 22-0.6" DYWIDAG Strand Tendons and 144 Type 27-0.6" DYWIDAG Strand Tendons.
