In the bridge over the North Umpqua River at Winchester in 1924, McCullough made far greater use of classic detailing than on any other bridge he built in Oregon. He started the design process by sketching out what he envisioned for the site, or, as design engineer Ivan Merchant recalled, to lay out the overall job. He would pick up paper and pencil and say, Now this is about what you are going to do. And he drew this spandrel arch in there and the roadwayand there it is. Go ahead And of course about every two or three weeks hed come back and see how you were getting along.

The Winchester bridge has rows of dentils and seven 112-foot spans with gothic-arched curtain walls and railing panels. McCullough also added pedestrian observation balconies above each abutment pier and decorated them with Tudor panels inlaid with diamond-shaped red tiles, all designed to complement the natural beauty of the hilly location.
