One of a couple of small trestle bridges in Chaska, this structure crosses East Chaska Creek.
It is believed that this bridge was built in 1956, prior to the C&NW acquisition of the route. It is a standard bridge, with 4 spans resting on wooden piles.
Overall, this bridge remains in good condition. It has an unknown future.
The author has ranked this bridge as being minimally significant, due to the common design.
The photo above is an overview. The bridge can easily be accessed from Chaska Boulevard.
