This unusual girder bridge crosses US-24 (Adams Street) near I-474.
Originally built in 1912, the bridge inisially consisted of four girder spans to cross Kickapoo Creek Road. These spans were originally built for two tracks.
In 1987, it was extended to cross US-24. The new spans featured a welded Through Girder design.
The bridge currently features 9 spans, 4 of each type of girder; with one I-beam on the center pier. Overall, the bridge appears to be in good condition.
The author has ranked this bridge as being locally significant, due to the common design. However, the creativity of extending the historic bridge should not be overlooked.
The photo above is looking at the older spans.
