The Caldwell Historic District in Caldwell, Idaho, is an area of approximately four acres in downtown Caldwell along Main Street, South 7th Avenue, South Kimball Avenue, and Arthur Street. Fires in 1884 and in 1896 destroyed businesses in early Caldwell, and brick had become Caldwell's favored building material for downtown structures.: 50  In 1906 alone, brick construction on Main Street between South 7th and South Kimball Avenues included the Steunenberg Block, the Egleston Block, and expansion of the Lucas Block—soon known as the Little Block and later dubbed the Harmon Building. When the Caldwell Historic District was surveyed in 1982, many brick historic buildings adjacent to the district were not included.The district includes Romanesque Revival and modest commercial architecture, although some facades have been altered since construction.

McConnel. The site is where Oregon Trail pioneers forded the Boise River. The bridge was listed on the National Register of Historic Places in 2007.The Boise River and Canal Bridge replaced an earlier bridge known as the Canyon Hill Bridge, and when the new bridge was commissioned by Canyon County officials, it continued under the same name. Later, the bridge became known as Idaho Pacific Highway Bridge, Highway 30 Bridge, or Silver Bridge.The bridge road width, 19.5 ft (5.9 m), only allows for one automobile traffic lane, and vertical clearance is limited to 14.1 ft (4.3 m). These factors and that the bridge is beyond its functional lifespan have prompted Canyon County officials to consider refurbishing the Boise River and Canal Bridge as a pedestrian only bridge and building a new bridge for motorized traffic near the site.
