All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad 
  is His slave and Messenger. 
The translation of As-Siraat as bridge is a correct translation. Firstly, it corresponds to the authentic Hadeeth reported by Al-Bukhari and Muslim which was related by Abu Sa’eed Al-Khudri 
  regarding the believers seeing their Lord. It is a long Hadeeth and part of it reads: “…Then the bridge will be brought over Hellfire. We [the Companions] said: 'O Prophet of Allaah, what is the bridge? …” 
A bridge is considered a path (Siraat), because path is a name given to anything that is walked on.

Allaah Knows best.
