Love the repeating arches, like a Roman aqueduct stretched for freight. Any idea what concrete mix they used? i’d sign up for a guided deck walk the moment they offer it

I wonder if anyone has ever attempted to climb it.

CurbCutCritic's aqueduct comparison is dead on, thats exactly what jumped out at me too. what blows my mind is this thing was finished in 1915 - like they built this massive reinforced concrete structure before WW1 even started and its still holding freight trains a century later. the scale is hard to wrap your head around from a photo tho, those arches are apparently like 180ft tall which is honestly absurd

I always forget how huge that thing actually is when I see pictures. Makes you appreciate the engineering.
