Impressive Denargo Bridge under construction on N Line
The first commuter train bridge along the N Line if you're traveling south to north is under construction near downtown Denver.
It's the Denargo bridge and it runs parallel to Denargo Street across the old Union Pacific tracks and the South Platte River.
Denargo Bridge under construction north of downtown Denver. September 2016
This bridge has 17 spans consisting of pre-cast concrete girders. Construction workers spent 10 days in September setting the girders. It is not designed for pedestrian or bicycle access, but it is designed with two sets of tracks so trains can pass each other going opposite directions on the bridge.
The rails for the tracks will be directly attached to the bridge deck. Doing it that way eliminates the need for ties or ballast. Ballast is the rocks you often see between rails and ties.
