WHAT IS UNDER THE CITY OF MONROE

    If you are considering locating a heavy industrial facility to Monroe, such as a stamping plant or even a blast furnace, you will find a limestone bedrock foundation capable of supporting it.

   The city of Monroe has three major trunk line railroads that run from Toledo to Detroit.  With Federal support and local finincing tracks have been consolidated and an underpass provided under two of the three rail lines.  Achieving this while maintaining rail traffic has been a major engineering challenge.  

This image is scanned from a 4 by 5 inch sheet of Fuigi Velvia film exposed with a 210 mm lens.  The exposture used is f6.8 @ 125th of a second.  Increased depth of field was obtained by tilting and moving the lens board.   The full photo as scanned is 4391 by 5567 pixels and requires 71.660 MB of storage as a TIFF file.
