Located just south of Thompson along County Road 17 at 4th Avenue, this standard concrete slab bridge crosses an unnamed ditch.
Built in 1922, the bridge features three concrete slab spans, set onto concrete substructures. These spans follow a standard design for the Great Northern.
This style bridge was commonly used to cross small streams because of the cheap cost, easy installation and limited maintenance required. Typically, these were used to replace wooden trestles. A span like this could often be built while only interrupting traffic for short times.
Overall, the bridge appears to be in fair to poor condition, with deterioration noted throughout the structure.

The author has ranked the bridge as being minimally significant, due to the common design.
