The reason of its abandonment was because the Railroad was rerouted for cost efficiency, due to the nature of the route being a dangerous one with a high likelihood of landslides/erosions from the bluffs in close proximity to the tracks, flooding from the river bottoms & swamps, plus the engineer of either freight, passenger or mail trains needing to take the train slow in order to account for the potential hazards.
The rerouting of the line still occurred even despite protests from the townsfolk of the towns of Etter & Eggleston, because of the fact that rerouting the railroad would be a major inconvenience to them as the proposed line would be surrounded by swamps, marshes & wetlands, making new stations for their townships impossible to build and resulting in them losing a mode of transportation.

As for the bridge design, not much is known other than what is visible on google maps, and with that being said, there are 6 concrete(?) pylons/piers with an assumption that there were +/- 7 spans to connect the piers/solid ground to get the train across the northern channel of the Cannon River.
