The railroad bridge at Burlington was built for the Chicago, Burlington, and Quincy Railroad for its Chicago to Denver route. The bridge is now owned and operated by the BNSF as a heavily used mainline. A US Coast Guard study found that this bridge was third among those that were struck most often by barges. It was hit 92 times between 1992 and 2001. As a result, BNSF is reported to be planning to replace the swing span with a lift bridge. This would vastly widen the navigation channel since you could use the full width of the former swing span instead of only one side of the center of the swing span.
Some of these photos were taken during a foggy, overcast, and rainy day spring day, while the rest were shot a few months later on a hot summer afternoon.
