There are currently only two highway bridges spanned over the Bosphorus in Istanbul, which are hung by two main cables a with total length of 1,400 Meters (4,593 ft.) and diameters of more than 2.5 Meters (8.2 ft.) each. These main cables consist of numerous, smaller and high-strength steel wires which are pressed together by 84 concrete cable clamps.
the art of Spanish Bridge Design
Sensitive to aesthetics, Leonardo Fernández Troyano designed a slender deck supported by two inclined planes of cables that connect to the sculptural V-shaped towers, representing a gateway from the city into the park (Figure 5). Moreover, the uniquely shaped towers with rounded profiles on the top engender thoughts of symbolic significance, perhaps evoking the sun. On a more light-hearted take, some locals call the two bridges over the M-40 and R-3 the “Chupa Chups Bridges,” as a nod to the lollipop shaped towers (Figure 6).

Attempts have been made to provide a simpler anchorage for structural cables by passing the cable through an opening in an anchorage block and securing the cable at the rear of the block. A specialized form of such an anchorage arrangement is shown in Pat. 2,914,783 to Hoyden et a1. Such anchorages are not completely satisfactory, however, as they do not uniformly distribute the load throughout the anchorage concrete, and, depending upon the particular design, may also experience difficulty due to poor bond of metalwork with concrete.
At 2,682 meters long and a center span of 1,550 meters, the Osman Gazi Bridge is the fourth longest suspension bridge in the world and has become the longest suspension bridge IHI has built overseas. IHI Group undertook the entire construction of the bridge as the single contractor and completed and opened it for traffic in June 2016.
These basic bridges typically span relatively short distances. In order to build a beam bridge (also known as a girder bridge), all you need is a rigid horizontal structure (a beam) and two supports, one at each end, to rest it on. These things support the downward weight of the bridge and any traffic traveling over it.
It is the world’s largest (but not the longest) steel arch bridge. The bridge carries roads for vehicles and railroads as well as bicycle and pedestrian traffic between the North Shore and the central business district of the city. The beautiful view of the bridge with the harbour and the Sydney Opera House form the so familiar and wonderful skyline of the city.
Haugh Of Drimmie, Suspension Bridge
(Location cited as NO 170 502). Haughs of Drimmie. Double cantilever bridge, probably c. 1830, engineer John Justice, Jnr. A handsome wrought-iron bridge with iron-framed timber deck supported by diagonal rods. Under the deck is a liight inverted bowed truss, built up of circular-section rods.
Tackling tricky aerodynamics paved the way to the world’s longest suspension bridge. The great belt link has united Denmark and moved boundaries within bridge engineering.
The link across the Great Belt is 18 km long and connects the eastern and western parts of Denmark. It consists of two bridges and a tunnel, and with a main span of 1,624 metres, the East Bridge was designed to have the longest suspension span in the world.
