Design
The bridge uses the Brown truss system, consisting of diagonal compression beams and almost vertical tension members (slanting in at the top toward the center of the span) was patented by Josiah Brown of Buffalo, New York in 1857. A timber bearing Brown's name was discovered during repair work carried out in 1913.
The bridge is 125 feet (38 m) long, and originally rested on wooden pilings. As is typical for covered bridges, its gabled roof is covered with creosote shingles.

Famous quotes containing the word design:
“I begin with a design for a hearse.
For Christ’s sake not black—
nor white either—and not polished!
Let it be weathered—like a farm wagon—”

—Henry David Thoreau (1817–1862)
“You can make as good a design out of an American turkey as a Japanese out of his native stork.”
