I would not categorize this truss as a Childs, it is a Long variant.

Though it curiously has the Double Posts in Childs' patent (Unlike the Sherman variant "Childs" Trusses) There are the Counter Braces ala Long and the Braces join the posts in Long fashion as opposed to Childs - And more importantly the Truss Rods are configured opposite of how a Childs conveys loads from panel to panel, they would be ascending not descending.

I suspect the rods were either added post build or were used in lieu of the pre-tensioning wedges in the Long patent.

I've visited the Sherman variants, but not this bridge and am somewhat reluctant to edit the page based solely on photographs. At the same time I think it a bit silly to miscategorize the bridge simply because the Historic marker was written based on assumption over research.

Does anyone who has visited have better shots, or an opinion as to type?

Hadn't realized anyone had added this here.

Some may have interest in these followups -

Though greatly diminished in numbers, these were quite common in mill complexes here in New England.

As far as a going name for this category of sky-bridge, The National Park Service (my current employer) refers to them as "Industrial Bridges" as can be seen in this technical bulletin.

Closed after an inspection Friday, though it is said the recommendation is for repair.

Thought I'd nailed down which was which with portal details...

You're right, the right PE and "contractor" are key. I've a friend I've done some preservation work with in the Roanoke area, he's done some structural work on one of the Woolwine examples, I'll make sure he's aware of this development.

Excepting the Wooden / Iron "Combination" trusses.

I agree completely.

Even the hundreds of primary reports filed from that bridge do not make it historic.

Sadly, it is almost as if the remaining Storrs spans have been targeted for removal.

Yes - It is a tensile loadpath intended augment the stringers.

The lack of sufficient freeboard for such, is likely why the system is missing from the other span.

A re-dedication is planned for this coming Monday.

This very funky Burr has a bit of an unusual story behind it, those with interest in wooden spans may wish to click in > https://bridgewright.wordpress.com/2015/08/31/the-curiosity-...

Not historic, not a truss, I don't even consider it a covered bridge.

It's a decoration dragging down the stringers holding it up.

Lots of layers to this onionskin, the spot is/was ripe with bridges, both RR and highway, with a succession of losses to highwater. The highway bridges were often owned/built by two different jurisdictions with the town line running down the middle of the island. Losses and replacement were not always concurrent - No pun intended.

Wooden RR spans were sometimes saved by leaving loaded cars in them in anticipation.
