The first bridge to the Bosphorus

The first bridge to the Bosphorus Strait: The works on the Yavuz Sultan Selim Bridge, which will bring the two sides of Istanbul together for the third time, continue. So when did the two sides of Istanbul meet for the first time?
THE FIRST BRIDGE OF ISTANBUL STREET WAS PERSE BRIDGE
Dozens of bridges with unique stories were built until they reached the third bridge in Istanbul. The first known bridge in Istanbul BC. It was built by the Persian King. Built for the first time by the Persian King Darius, the bridge brought the two sides together. Do not cross the bridge. Despite the difficult conditions of the time, he carried the Persian Army on his back.
King Darius gave the order. The ships were lined up one after another in a very short time, between Rumeli Fortress and Anadolu Fortress, which are determined as the narrowest point of the Bosphorus. Thus, the Persian Army passed from one collar to the other on these ships. According to legend, King Darius settled at the point where Rumeli Fortress is located today and watched the army pass.
IMMEDIATING IMMEDIATELY BRIDGE BRIDGE
A similar bridge was built once again during the Byzantine Period. This time it was built by the Byzantine Emperor Heraclius in Sarayburnu with a small margin. Because Heraclius had a fear of the sea.
Again, they were lined up and combined one after another so that the ships could cross the Heraclius waters and cross the other side. Just arranging the ships one after another was not enough. The Emperor saw the waters of the sea again when he was on the bridge, was afraid again and could not cross again. Thereupon, the ships were surrounded by bushes, and Heraclius was prevented from seeing the sea. Thus, Heraclius was enabled to pass from one collar to another.
Here are the first bridges built in Istanbul under the conditions of the time. Now, the 3rd Bridge is on Yavuz Sultan Selim Bridge.
