When you’re living in a city, the skies at night are fairly underwhelming. The shots you will get are the well lit buildings and bridges. A rare time you will find a place to shoot light trails from passing cars. Winnipeg has little traffic for light trails after dark. I’m not sure as to why, there is enough traffic, but perhaps not enough places from where to shoot that live traffic. However you turn it, in Winnipeg one will end up shooting this bridge.
It is now nearly world famous, in Manitoba. Shooting it in winter or summer makes little difference, as long as the skies are nice and clear. Sometimes, the sky over Winnipeg is lit up.
