Plasticville O Scale 45974 Pedestrian Bridge MIB for MTH, Lionel, Williams, Atlas and Weaver O Scale trains. The bridge kit is still sealed in its box.The bridge is molded in green plastic. The picture of the box above shows the bridge in the lower center. What is quite nice about these bridges is the ability to easily modify them to adapt to your layout. The second and third pics show what I did on my layout using parts from 6 bridges. I will discount shipping for multiple purchases of the bridges.
