From the web I quote, translated: Yalnızgöz Bridge is the continuation of the II. Bayezid Bridge, which was built by the architect Hayrettin by Bayezid II in H: 893-M: 1488. Approximately a hundred years after the construction of the II. Bayezid Bridge, it was built by Mimar Sinan in 1567 by Sultan Selim II when the Tunca River formed a new bed for itself. The bridge, which connects the city center to the II. Bayezid Complex, was made of cut stone in addition to the II. Bayezid Bridge. It has a single arch and the arch span is 6.6 meters. It is called by this name because it is single arched and so “single-eyed”. Due to floods, the ground was raised in 1611 and a third passage with multiple arches was added to provide the speed of water flow. There is a walking area called Hanım Saraylı Garden to the east of this third section. (Edirne Travel Guide, 2013, p.61) Osman Nuri Peremeci says, “The Yalnızgöz Bridge is a single-eyed bridge built by Mimar Sinan in the name of Selim II, with a span of 6.60 m., connecting Edirne to the Sultan II. Bayezid Bridge, and is an extension of the II. Bayezid Bridge.” The name of the bridge is not included in the biographies written by Mimar Sinan.
