The bridge itself is the typical 1970s and 1980s economical style steel girder with concrete deck and concrete piers. It should last 100 years or more with only routine painting and inspections.
The previous bridges in this location did not last that long. According to Mary Costello (Climbing The Mississippi River Bridge By Bridge, Volume 2), the first crossing here was a ferry service. A 3 span steel truss bridge was built in 1900. It was destoryed by ice in the spring of 1906. A new metal truss bridge was built in 1907. Due to being very narrow and light, it never was the bridge that it should have been. It did, however, survive for 70 years.
