You're right, the bridge is very narrow and the lens has a very long field, which makes the picture a bit deceptive (useful also to give the impression of a concentrated crowd). The bridge is about 6 metres wide (two narrow car lanes) but the farthest visible point is about 250 metres away. So it could be approximately 1500 square metres, and a crowd of about 1000-2000 people, although those who are actually visible are far less. Nice tool though, I'll use it again!
