Building the railroad that Went to Sea with photos.
Page 6
Building piers for the concrete arch railroad bridges continued.
The base and spandrel wall forms were built in Miami and numbered for
assembly on site.
The curved arch and the walls were barged to the location.
The arch forms are in place and a floor is being laid.
The spandrel walls are placed on top of the completed arch.

Above is a close-up view of traveling concrete
plant's track and the mixer drum in the upper right corner. Concrete was
mixed and poured as the mixer slowly moved across the forms setting on
piers.
A top view of a series of arches in the Lower
Keys after the wooden forms have been removed. Note that the center portion
is hollow to be filled later and the crossties laid on the fill. This will
absorb the shock and vibration as well as be a quieter ride. The track
to the right is a work track for derricks, etc. to have easy access.
This concludes the presentation of construction
railbeds. Now for a look at some of the equipment used in construction. |
