Boise River and Canal Bridge, bridge in United States of America
The Boise River and Canal Bridge is a historic bridge in Caldwell, Idaho that crosses the Boise River. It has three sections supporting one lane of traffic, a roadway width of about 19.5 feet (6 meters), and a clearance height of roughly 14 feet (4 meters), making it unsuitable for large vehicles.
The bridge was built in 1922 by the American Bridge Company and designed by city engineer Fred H. McConnel. It stands on a site where Oregon Trail travelers once forded the Boise River, and it was added to the National Register of Historic Places in 2007.
The bridge carries names that reflect its history: Canyon Hill Bridge, Idaho Pacific Highway Bridge, and Silver Bridge. These names show which roads and places it has connected over time.
Access is straightforward, but note that the roadway is very narrow and only one vehicle can pass at a time. The area around the bridge is quiet and inviting for walking or biking, especially if you take time for slow exploration.
The bridge was built using a Warren camelback through-truss design, a sophisticated construction technique where angled metal pieces distribute weight. Today, Canyon County officials are discussing converting it into a pedestrians-only and bicycle bridge while a new crossing for vehicles might be built nearby.
