[QUOT]6.2.2 The OVERPASS
The OVERPASS structure extends acoss the minor axis of the TRACK. The OVERPASS is constructed of 1-1/2 inch O.D. steel pipe and connecting hardware.[/quote]
So the official specs call for the overpass to be made of entirely steel pipe, however the team setup calls for 1in Iron pipe encased in 1-1/4in pvc pipe drawings, assembly instructions and a BOM can be found at
