Its realization took almost ten years as a result of revisions needed to comply with UNESCO regulations requiring it not to disturb the old city's skyline. He designed and built a project named "Larus Palas" worth US$ 30 million in the Göktürk neighborhood of Istanbul's Eyüp district, which was completed in 2013 and consists of 82 domiciles, 18 stores as well as facilities for sports, recreation and social activities.

It is flanked by viaducts on both sides which connect the bridge with the metro tunnels on each side of the Golden Horn. Nine cables are connected to each side of the two towers in harp-design starting at a height of 47 m (154 ft). To reinforce the soft bedrock, dozens of steel pipe piles with diameters of 1,800 mm (71 in) and 2,500 mm (98 in), supplied from Europe, were driven more than 30 m (98 ft) deep into

192-528: The Fatih district (at the southern end of the M2 line.) The idea of the bridge was first mooted in 1952 but only really came to life during the period when Kadir Topbaş was mayor of Istanbul (2004-17).

Controlled from a room on a platform between the bridge and the shoreline, the swing bridge turns at a right angle about the vertical axis after lifting, and provides about 40-metre-wide (130 ft) free clearance within four to six minutes. The swing bridge

Even the successful design, by architect Hakan Kıran , was considered controversial. In November 2009, the proposed height of the towers was reduced from a projected 82 m (269 ft) to 65 m (213 ft) after UNESCO threatened to remove Istanbul from its list of World Heritage sites .

The deck is a 4.45-metre-high (14.6 ft) box girder . On

456-537: The pier foundations necessitated a redesign of the project. The design of the swing bridge operator's command building also had to be revised when the wall of a Byzantine-era basilica and a graveyard on the same bank came to light. The eventual design pays homage to the city's maritime heritage with support towers shaped to look like horns and hull-shaped supports for the platforms.
