This large girder bridge looks quite out of place in the present day, crossing nothing but an empty field.
However, when it was built, it originally crossed the Boyer River; a river that flooded often and required a large trestle.
Because of the continued flooding of the area, a series of diversion and channelization projects took place throughout first half of the 21st Century. This included the rerouting of the Boyer River, and filling of the channel under this bridge.
The bridge that remains is a large 3 span deck girder. The piers are steel bents, set on stone piers. In addition, the abutments are made of stone as well.
Today, the bridge is in good condition. The author has ranked this bridge as locally significant, due to the common design.
