Plaque of the Spiral Bridge This bridge replaced the Hastings Spiral Bridge, which was unique for its spiral west approach. The main span was of a Parker design. Because of the increase in vehicular traffic and lack of funds to save the bridge, it was subsequentially demolished as soon as the new bridge was opened to traffic.

This public domain image shows the Spiral Bridge on a postcard from the era. This was the only spiral bridge built in the United States - two others reportedly were built in Europe. There is a high bluff on the north side of the Mississippi River. This requires a long approach from the south in order to span the river at proper height and reach the bluff. The spiral allowed the bridge to terminate in downtown Hastings.
Drivers would enter the bridge in Hastings and make one complete circle before crossing the bridge. As it reached the end of its useful life, it was limited to 4 tons. After the new bridge was built, the city of Hastings did not have funds to restore and maintain the bridge, so it was lost.
The citizens of Hastings felt they lost a great landmark, and a replica has been built in a nearby park.
