So Edmonton is in the process of expanding the Light Rail Transit. Part of the process involves crossing the river.
They are now in the middle of tearing down what once was a foot bridge to replace it with a new bridge for the train to cross over to the other side
I hope the footbridge was not used much because it seems like a practical place to put the new bridge in. It doesn't sound like you'd want to walk next to the train though! good shot.
@olivetreeann Ann it was us3d a lot as it connected two parks on either side of the river. If they do what they did with the other LRT bridge the train is on top pedestrians on the bottom
