Description 

"The 1891 9-panel Howe pony truss bridge is of riveted construction. It rests on bearing plates supported on 1917 concrete abutments with wingwalls. It has timber stringers and deck. The deck is cambered, but not the truss. Three blast plates remain. Knee braces are used at each floorbeam rather than outriggers. The floorbeams are attached to only the inside plate of the bottom chord. The bridge is extremely well preserved, and it is one of the most distinctive early RR spans in the area."

Milford Road Bridge

Thanks Tony! Ribbon lacing is a good name for it; probably the proper name, so I added that to the photo caption.

This is a very unique span Andrew! I love the Ribbon-lacing seen in pic #6. you don't see it in very many bridges.
