Caption: The Skew Arch Bridge
Additional Description: This may be the only skewed masonry bridge remaining in the United States. Built in 1832-34 to carry a wagon road over the tracks of Incline 6, it was constructed on a skewed, or twisted angle. The road and the railroad could then cross, with each maintaining their straight path up the slope.
Notice that the arch jambs are not at right angles with the face of the bridge. The bridge abutments are also offset and not directly across from each other. See how the stones were cut and laid in a diagonan direction.
This bridge has withstood the elements for over one hundred and fifty years and is well preserved. Its fine architecture stands in tribute to the skills of the engineers and stone masons who built it.
