Bridging the gap

Dan S.'s picture

I have completed a couple of bridges to span the gaps in the roadbed and this proved to be quite an enjoyable process. the first is a combination through truss and deck girder bridge. The truss is simply a walthers kit and as in the past i have found this kit to be a joy to assemble. The deck girder section is just some micro engineering girders. There is still a bent to be fitted on the last girder joint.

 

 

The second bridge is a tall steel viaduct.

 

The towers for this trestle were scratchbuilt from styrene wood and  brass I beam. The girders are from the walthers through girder bridge kit with the rounded corners cut off. This project was time consuming yet very satisfying. The finished structure is 3 feet long and 14 inches above the surrounding scenery at its highest. The radius of the curve is 30 inches. The core of the bridge is made from MDF and the girders fastened to them. there are only girders on the visible side as there is no possible way to view the bridge from the other side.

More please

I'm really enjoying your pics Dan.  Any chance of seeing a layout plan, or hearing more about what you're building?

Question Answered

Your trestle picture and explanation just answered my question or how to do one of my trestles. On sat at op sec three of my friends all discussed this exact approach in building trestle. Agree about back and in my case it is in the 70" off floor range so top is not important either except for video.
