Richter Anchor Metal Bridge
built by George Hardy

The main feature of these designs is the metal construction, not the stones.  The beams were adjustable, set to length with two bolts and nuts.  Beams were made in "compression" style (an "L" cross section) and "tension" style (flat bar stock).  Both styles of beams were made in the fixed length of 100 mm.  Adjustable beams (both compression and tension) could be set to any length from 37 to 113 mm.  This range was covered by four different beam sizes (excluding the possibilities that can be achieved by mixing of the parts).  The beams were made from nickel-plated iron and brass bolts/nuts -- a most attractive combination.  Roadbeds were painted to look like wood planking, and railings were included. 

Note how attractive the bridge trusses are.

The plank roadbed looks very nice also.  I chose the under-truss design because the roadbed is easier to see.

Notice the cross bracing to prevent lateral distortion.

The entire bridge. I chose a different stone pier design from the selection of the ones Richter used for his bridges.

The stone construction for the Richter designs is quite routine and dull.  Note the repetition of the layer designs.

The design of this stone pier was used for three different metal bridges, showing that Richter considered the stones a background part of the overall picture.  The metal bridge trusses are the stars.
