| Summary: | The J.P. Magufuli extradosed bridge is currently under construction. This bridge crossing Lake Victoria has an overall length of 3,000 m and a deck width of 28.45 m to accommodate 4 lanes of 3.5 m wide carriageways of vehicular traffic, a shoulder of 2.5 m+2.5 m for emergency parking and vehicle breakdown on each side, a 2.5 m+2.5 m footpath for pedestrians on each side, and a median of 2.45 m. The structural arrangement of the main bridge is 100 m+160 m + 160 m+100 m = 520 m, and the approach bridge prestressed concrete (PSC) beam bridge L = 2,480 m (including 31@40=1,240 m on each side). The superstructure is an extradosed bridge with an RCC deck with three RCC pylons 18.856 m in height. The girder heights at the mid-span and end-span are 5.4 m and 3.2 m, respectively. This paper discusses the construction aspects of the J.P. Magufuli bridge along with the details of a special traveling formwork (Form-Traveller) that is used to enable balanced cantilever construction, Pylons, PC House construction for the Pile Cap, and Deck Slab Partial Depth Panel for Deck Slab Construction. |
