Figures 59 and 60: Elevation and sections of the bridges The two navigation channel bridges, namely Brunei Channel Bridge (BCB) and Eastern Channel Bridge (ECB) are crossed by cable stayed bridge. The BCB will be a gateway between the Brunei-Muara and the Temburong districts and is designed as an iconic bridge. The ECB has a similar form. To cater for future navigation needs of trade and navy vessels, BCB with a single tower has a main span of 145m, Figure 59. The ECB crosses the international waterway with a main span of 260m between two towers, Figure 60. The towers are crowned with the Islamic star and crescent symbol. Both bridges have a concrete ladder beam deck which comprises of two edge girders and cross beams between the edge girders, and concrete slab spanning between the cross beams. Brunei being an Islamic country, visually the concrete towers have been designed to be unique and instantly recognisable with qualities that incorporate Islamic architectural features, Figures 61, 62 and 63. In terms of engineering, the towers are A-shaped towers, Figure 64, but visually look like an arched gateway. The four architraves of the arch symbolise the four districts of Brunei and the narrow slit window on the top symbolises the unity of the four districts with Koranic words at the apex of the arch. 1/2018 Figure 64: Bridge Towers As the project director for both the feasibility study and detail design, and as the Engineer for all the civil and M&E contracts, this project has given me immense satisfaction to significantly contribute to the development of Brunei and the opportunity to design a bridge with Islamic features.
