Here is my collection of my custom LEGO roads version sp02. Basically just a flat sheet of 1x2 bricks on their sides.
COLTC LEGO Display at Columbus Great Train Expo Jan 2006, with my bridge ver. 10, hill, and Windmill
This bridge was meant for a dual deck Rail bridge that could be pivoted up so we could access the inside of our display. The unit worked but I never modified the RR track to make it truly functional. Original show date GTE 2006.
