The Peace Bridge in Calgary

I passed the construction site everyday, and today I finally got a chance to check the location from Google Map:



From the map you can see there are already one bridge (E) and 2 pedestrian bridges nearby: The (A) is on the east, 920 meters away, the (D) is on the west, 300 meters away. These 2 bridges have overhead bridges to walk through the busy Memorial Drive. But the Peace Bridge (C) is not having an overhead, so people have to walk through the Memorial Drive.
So, should we install traffic lights to help crossing the street? Wait, on the 270 meters east, (B) site already has traffic lights.

The Peace Bridge is totally a waste of money.
