Walnut Lane bridge over the Wissahickon creek

The Walnut lane bridge was certainly most of my wanting to reproduce something similar in HO scale. Although the Walnut lane bridge is a roadway bridge with cantilevered sidewalks, the main structural elements for a railroad bridge would be similar, and I did not try to reproduce an exact copy this bridge, which is right in my neighborhood.

The bridge was built in 1908 and at that time was the longest masonry arch span in the world, just now finishing a restoration.
