Pope Street Bridge is a two-lane, earth-filled, closed-spandrel masonry-arch bridge consisting of three spans. The masonry structure is built of cut stone of random sizes laid in irregular courses. Both railings are of square-cut stone. At 177 feet long, it is the longest masonry arch bridge in California. It is an archetype among California bridges including the structural and architectural elements such as the roadway and railing peaking at the center span, the pyramidal buttressing of the river piers and the decorative coping at the top and bottom of the railing.
