The John Day River Bridge, near Astoria, Oregon was built with a continuous deck length of 1,105 ft. (340 m). The rationale for designing the John Day River Bridge with an unusually long continuous deck is in part based on the site's very mild climate. Overall temperature changes in the deck are in the range of 50 F (28 C). The objective was to mon
