Madeenah will have seven gates when the Dajjaal comes


I saw a hadith in Sahi-al-Bukhari, (rough translation) stating when Ad-Dajjal comes there will be eight gates in Madina, and each gate will have two angels as a guard to prevent Dajjal to enter Madina.
As far as my knowledge goes Madina at this present time do not have any gates, but only paths.
My question is does the word gate in the hadith refers to pathways, if it does then how many pathways are there to Madina.
