The Bosphorus Bridge, also called the First Bosphorus Bridge (Turkish: Boğaziçi Köprüsü or 1. Boğaziçi Köprüsü) is a bridge in Istanbul, Turkey spanning the Bosphorus strait (Turkish: Boğaziçi).
The bridge is located between Ortaköy (European side) and Beylerbeyi (Asian side).
It is a gravity anchored suspension bridge with steel pylons and inclined hangers.
The aerodynamic deck is hanging on zigzag steel cables. It is 1,510 m long with a deck width of 39 m.
The distance between the towers (main span) is 1,074 m (World rank: 15th) and their height over road level is 105 m.
The clearance of the bridge from sea level is 64 m.
It was the 4th longest suspension bridge span in the world when completed in 1973, and the longest outside the United States of America.
The decision to build a bridge across the Bosphorus was taken in 1957 by Prime Minister Adnan Menderes. For the structural engineering work, a contract was signed with the British firm Freeman Fox & Partners in 1968. The bridge was designed by the famous British civil engineer Sir Gilbert Roberts who also designed the Humber Bridge, Severn Bridge, Forth Road Bridge, Auckland Harbour Bridge and the Volta River Bridge. The construction started in February 1970, the ceremonies were attended by President Cevdet Sunay and Prime Minister Süleyman Demirel. The construction was carried out by the Turkish firm Enka Construction & Industry Co. along with the co-contractors Cleveland Bridge & Engineering Co. Ltd. (England) and Hochtief AG (Germany). 35 engineers and 400 men worked on the project.

It was completed on October 30, 1973, one day after the 50th anniversary of the founding of the Republic of Turkey, and opened by President Fahri Korutürk and Prime Minister Naim Talu.
Ernest Frederick, a civil engineer working for the US government and stationed in Turkey at the time, was the first American to cross the bridge.
American comedian and Ambassador for UNICEF Danny Kaye, dressed like a clown, followed him with a pack of Turkish children.
As a huge crowd of people started to run after them, the bridge began to vibrate, and the crowd had to be held back to avoid any damage.
The cost of the bridge amounted to USD 200 million.

The highway bridge has a total width of eight lanes. Each direction has three lanes for vehicular traffic plus one emergency lane and one sidewalk.
On weekday mornings, commuter traffic flows mostly westbound to the European part, so four of the six lanes run westbound and only two eastbound.
Conversely, on weekday evenings, four lanes are dedicated to eastbound traffic and two lanes only to westbound.
In the first four years, pedestrians could walk over the bridge, reaching it with elevators inside the towers on both sides.
No pedestrians and commercial vehicles like trucks are allowed to use the bridge today.
Nowadays, around 180,000 vehicles pass daily in both directions, almost 85% being automobiles.
On December 29, 1997, the one-billionth vehicle passed the bridge. Fully loaded, the bridge sags about 90cm in the middle of the span.
It is a toll bridge, and a toll plaza with 13 toll booths is situated near the bridge on the Asian side.
A Toll is charged for passing from Europe to Asia, but not for passing in the reverse direction.
Since 1999, some of the toll booths (#9 - #13), located to the far left as motorists approach them, are unmanned and equipped only with a remote payment system (Turkish: OGS) in order to speed up traffic.
In addition to OGS, another toll pay system with special magnetic cards (Turkish: KGS) was put in service for use at specific toll booths in 2005. From April 03, 2006, toll booths will accept only KGS and OGS.
From this date on, cash payments will be accepted only at the Fatih Sultan Mehmet Bridge, about five kilometres to the north. In 2006 the toll was 3.00 YTL or about $2.00.

The Intercontinental Istanbul Eurasia Marathon, organized annually in October, starts from the Anatolian part of Istanbul, crosses the Bosphorus on the bridge and ends in the European part during which the bridge is closed to the vehicular traffic.
Visitors to Istanbul in October can sign up for the 'fun run' at many points round the city and take the opportunity to cross the bridge by foot - many take picnics to enjoy the view.
Jumping from the bridge is a rather common method to commit suicide.
In 2001, 146 persons attempted to jump from the two Bosphorus bridges, and 24 of them lost their lives. In 2002, 38 persons died after 190 suicide attempts by jumping.

On May 15, 2005 at 7.00 local time, U.S. tennis star Venus Williams played a show game with Turkish standout İpek Şenoğlu on the bridge, the first tennis match ever to be played on two continents. The event was organized as a promotion ahead of the 2005 WTA’s Istanbul Cup and lasted five minutes only on the north side of the bridge. After the exhibition, they both threw a tennis ball into the Bosphorus.
On July 17, 2005 at 10.30 local time, British Formula One driver David Coulthard drove his Red Bull racing car on the bridge first from the European side to the Asian side, and then turning with a spectacular powerslide at the toll plaza back to the European side for show. He parked his car in the garden of Dolmabahçe Palace where his ride had started.
During his ride to the Turkish Grand Prix at Istanbul Racing Circuit on August 21, 2005, David Coulthard was picked up by the automatic surveillance system and charged with a fine of 20 Euro when he passed through the toll booths without payment, as only the president, traffic police and emergency workers have the right to cross the bridge for nothing. His team accepted to pay for him.
Since April 23, 2007, a fully computerized LED lighting system of changing colours illuminates the bridge at night.

On a merrier point of view, it is a popular belief that a wish made while going under the bridge will come true.

The Bosporus or Bosphorus, also known as the Istanbul Strait, (Turkish: İstanbul Boğazı) (Greek: ????????) is a strait that forms the boundary between the European part (Rumelia) of Turkey and its Asian part (Anatolia).
The world's narrowest strait used for international navigation, it connects the Black Sea with the Sea of Marmara (which is connected by the Dardanelles to the Aegean Sea, and thereby to the Mediterranean Sea).
It is approximately 30 km long, with a maximum width of 3,700 metres at the northern entrance, and a minimum width of 700 metres between Kandilli and Aşiyan; and 750 metres between Anadoluhisarı and Rumelihisarı.
The depth varies from 36 to 124 metres in midstream. The shores of the strait are heavily populated as the city of Istanbul (with a metropolitan area in excess of 11 million inhabitants) straddles it.

What is the Bosphorus or bosporus ?

The name Bosphorus means "ford of a cow" in ancient Greek and is derived from the myth of the maiden Io.

At Greeek Mitology;

Io was the daughter of Inachus, a river god. While Zeus was with Io, he caught a glimpse of Hera coming.
Zeus quickly turned Io into a heifer, swearing that he had never seen it before; that just now the earth gave birth to it; a newborn, from the earth. Hera did not believe Zeus.
She said how beautiful it was and asked Zeus if he would please make her a present of it.
Sorry as Zeus was, he saw that he could not refuse. He turned Io over to his wife who knew quite well how to keep Io away from him.
Hera gave Io into the charge of Argus, a one hundred-eyed watchman, who could sleep with some of his eyes on guard.
Zeus commanded Hermes, the messenger god, to find a way to kill Argus as Hermes was so clever. Hermes approached Argus as a shepherd playing on pan pipes.
"Come, sit by me. It's shady here. Just right for us!" Hermes said to Argus.
Hermes continued by playing a drowsy and monotonous song; a song about how the reeds became pan pipes.
It was the love story of Syrinx, a nymph and Pan, a satyr. Oh, how Pan had fallen in love with Syrinx, yet she not her.
Pan chased her and just as he was about to seize her, her sister nymphs turned her into reeds.
Pan told Syrinx, "Still you shall be mine." He cut the reeds and joined them with beeswax- thus the shepherd's pipe.
The combination of the story and music put most of Argus' eyes to sleep. Hermes in his quickness cut off Argus' head.
Io was only able to walk away still in her cow form. Hera soon found Io gone and Argus dead.
She took Argus' one hundred eyes and sprinkled them in the tail feathers of her sacred bird, the peacock.
Hera then sent a gad-fly (horse fly) to torment Io in her heifer form. Io swam across the Ionian Sea and the Bosphorus (Ford of a Cow) until she came to the Nile river.
There Zeus restored her to her human form. Io gave birth to Epaphus, of whom Hercules is a descendant.

Same story at another Greeek Mitology source

Zeus fell in love with Io and seduced her. To try to keep Hera from noticing he covered the world with a thick blanket of clouds.
This backfired, arousing Hera's suspicions. She came down from Mount Olympus and begain dispersing the clouds.
Zeus did some quick thinking and changed Io's form from being a lovely maiden. So as the clouds dispersed Hera found Zeus standing next to a white heifer.
He then swore that he had never seen the cow before, it had just sprang right out of the earth.
Seeing right through this Hera complimented the cow and asked to have it as a present.
As turning such a reasonable request down would have given the whole thing away, Zeus presented her with the cow.
She sent the cow away and arranged Arges to watch over it. Since Arges had a hundred eyes and could have some of them sleep while others were awake he made a fine watchman.
Desperate, Zeus sent Hermes to fetch Io. Disgused as a shepard, Hermes had to employ all his skill as a musician and story teller to gain Arges confidence and lull him to sleep.
Once asleep Hermes killed Arges. As a memorial, Hera took his eyes and set them into the tail of her favorite bird, the peacock.
While Io was now free Hera sent the mother of all gad-flys to sting the still bovine Io.
This pushed her near madness, trying to escape she wandered the world. During her wanders she came across Prometheus while chained.
He gave her hope. He predicted that she would have to wander for many years. But, she would eventually be changed back into human form and would bear a child.
He predicted that a decendent of this child would be a great hero and set him free.
His predictions came true. During her wanderings many geographical features where named after her including the Ionian Sea, and the Bosphorus (which means ford of the cow).
She eventually reached the Nile where Zeus did restore her to human form. She bore Epaphus and eleven generations later her descendant Hercules would set Prometheus free.
