This is the link to an amazing web page, which shows more than 100 traffic webcams in Bangkok. You only have to choose the cam, you want to see -> you will see the street etc. At Bangkok daytime (please be aware of the time shift) this web cam overview is an amazing tool!

There is a very nice Webcam on the roof of the Landmark Hotel, which shows both sides of the Sukhumvit Road (approximately Soi 7). The Webcam is turning around every x seconds.
