MSTR - Grasse River Bridge
The main span over the river is the only all-aluminum railroad span in the US. Built by Alcoa (serviced by MSTR) in 1946 as part of a line relocation to demonstrate the structural properties of aluminum for bridge-building.
The rest of the bridge was fabricated by Bethlehem Steel Co. and is made of standard steel.
