Other bridges are more important for their historical significance. Boothby's work in Princeton, New Jersey, on a bridge that was too narrow, might help preserve the bridge by having it listed as a historic landmark. The bridge looks like a stone wall built of fieldstones, except for the semi-circular arch that a small stream runs through. County men built the bridge in 1916. Maple trees and a couple of oaks shade the stream and the bridge in the summer.
Grassy banks lead down to the water.
If you lean against the bridge and touch the rough stones, you can feel the cracks in the spandrel walls. You can stick your fingers inside them and brush out some grout. The bridge needs serious repairs. Boothby proposes to build a new one of brick rather than the more costly stone. The contractor would install instruments in the bridge to monitor stresses and strains, especially any displacements in the spandrel walls.
