There's a lot of traffic around here

The photo shows a sign of the Cairo Metro in Egypt. The oldest metro systems in African continent. I took this photo in Tahrir Square right above Sadat station of the Cairo Metro. There's a lot of traffic around here. I used the underground station to cross the street. I didn't know that, but Cairo, Egypt was heavily-trafficked. From what I remember, the area from Tahrir Square to the Egyptian Musium looked like one of the most heavily-trafficked and it wasn't exactly easy to cross the street for a tourist. So that's why. The underground access was come in handy.
