Weisel Bridge
Posted April 6, 2010, by Nathan Holth (form3 [at] historicbridges [dot] org)

Todd,

As requested, please see the attached photos of a through truss grafted onto a slab. Sorry they are small, they came from what is left of Daniel Alwards website on the Internet Archive.

While I do not believe that either of these bridges should have been demolished like they were, since it is obvious bridges of its size could have at least been relocated and preserved elsewhere, I do agree that in cases where a historic bridge is being demolished, a solution such as these ones are far more appropriate than other more commonly seen forms of Section 106 mitigation, because it salvages a portion of the original bridge material.

Far too often, Section 106 mitigation does not involve the retention of any original bridge material aside from a builder plaque. Typical Section 106 mitigation in Pennsylvania is to use weathering steel instead of pre-stressed concrete beams, add cast a stone-shaped texture onto the concrete substructure, and use low-profile two-tube guardrails instead of New Jersey barriers. In my view this is an unacceptable form of mitigation.

In contrast, I do believe that grafting the original truss lines onto a pre-stressed slab bridge (along with a recordation of the bridge prior to demolition) more seriously captures the intended spirit of Section 106 when it is stipulated that the adverse effect of demolition should be mitigated, which in other words means that the initial anticipated loss of history would be reduced through the mitigation.

I wish historic bridges destined to be UCEB's could be dealt with like this bridge. I'd like to see a full size through truss get saved from the scrapheap by incorperating a modern deck and keep the trusses for their historic appearance purpose after they're relieved of their load bearing use. The countryside could see lesser UCEB's this way.

Year built -2004

Span length 64.0 ft.

Total length 65.9 ft.

Deck width 35.1 ft.

Material - Prestressed concrete

Design - Box beam or girders - Multiple

Deck - Concrete Cast-in-Place
