To be saved and moved to a local cemetary:
i go under the bridge it is amazing i used to ride over it but they built a new one they blocked the bridge because it is unstable do not go on it it is dangerous but it is very beautiful i live here still
listen i live right by the bridge and i have for 15 years it is a major place in my life they want to take it but i wont allow it
The bridge is a Camelback Pratt through truss bridge. The floorbeams which support the deck were placed at different locations along the vertical members in order to achieve a sloping deck. The deck was sloped to reconcile the bank elevations at each end of the bridge. This is an unusual solution to a common problem...trusses are more often set at differing elevations on the pier, so both the truss and deck slope, but the floorbeams are attached at the same location on the verticals.
The bottom chord is straight, it is the deck that rises on one end.
I think this may be somewhat of an optical illusion, it looks to me as if the deck isn't parallel to the bottom chord as is the norm. The deck is on an angle to accommodate the grade of the road maybe.
I've not seen another one like it Gene. Usually when the lower chord is not straight, it is curved like the upper chords on the Parker and Camelback trusses.
This is a peculiar design with the bottom chord in somewhat of an arch, and not parallel with the deck..does anyone know what this design would be called? Otherwise it is similar to Pratt designs.
