In an implementation, an overhead irrigation assembly includes a first support, a second support, and a span of pipeline supported between the first support and the second support. The overhead irrigation assembly also includes a first truss rod tensioned between the first support and the second support and a second truss rod tensioned between the first support and the second support. Spreaders are suspended from the span of pipeline that are configured to separate the first truss rod from the second truss rod. The overhead irrigation assembly also includes a third truss rod is also tensioned between the first support and the second support. The first truss rod, the second truss rod, and third truss rod are configured to maintain a generally bow shape in the span of pipeline.
