The only other timber truss type that had any longevity was the Lattice or Town truss which gained its strength from a tight web of overlapping diagonal members.

A lot of strip wood was used in the construction of this twin span truss bridge. It includes three bents, two bulkhead planks and a open deck for track ballasting. Go right and continue to follow the trail uphill as the bridge becomes more and more visible. The same rules apply to steel viaducts with single-panel bents.

The ability to divide the main arch span into separate ribs - once only possible with steel - was now a standard feature of these new concrete creations. Detailed chapters explain the construction and design of bridge abutments and piers, and the footings that connect them to the bridge.

Just like full size railroads soft soil tends to wash away or onto track during wet weather. It was replaced by a fill causeway in the s, and is now being salvaged for its timber. This ability to transfer the weight of the main span to the shore arms was also a major advantage during construction since there was no need for false work over the deepest parts of the river.
