Cocker Bridge
     The sidewall is solid cast in one piece.  Two sidewalls, a  ¼" thick roadbed and two deck supports compose one bridge section with a roadbed length of 26½".  Sections are mated to suit your layout along with a choice of seven or twelve inch wide roadbeds and a standard or soot finish.   Abutments, bases, piers and height extensions are available for a custom build.  Best to order these at the same time for color continuity.  Bridge sections ship separately.

Until now, I inserted a 2" piece at the joint between sections to make the arch length equal (as above).  This is no longer done and your bridge will  look like the one below.
