The bridge was jointly used by Northern Pacific and Union Pacific. To avoid using switches 2 sets of track were overlaid to occupy a single track. The advantage is there was no need to use switchtrack that would slow down the train. This kind of trackage is known as the gauntlet configuration (only one train can traverse the bridge at a time.
