Blenheim Bridge Interior Structure
Photographer: Howard C. Ohlhous
Taken: September 27, 2008
Caption: Blenheim Bridge Interior Structure
Additional Description: The wooden Burr Arch, curving up amongst the interior woodwork in the center of the bridge, is responsible for carrying a major portion of the bridge load. The trusses are of Long Truss design. The center truss is higher than the two outside ones. The center truss encloses a single arch of oak which reaches from below the lower chord on up to the ridgepole at the peak of the roof. It is really three concentric arches, one on top of another, and carefully blocked together to allow air to circulate among them.
