In 1931, the Rock Island realigned and upgraded its Trenton, MO, to Kansas City, MO, line with 76 miles of new and upgraded tracks costing 13.5 million dollars. As a part of the new construction project, a section of joint MILW/RI double track was built between Polo and Lawson. The original MILW single track DPG bridge over the Crooked River was replaced at this time with a much larger double track bridge just upstream on the new joint line.

The new bridge is still in service to this day with the Union Pacific and Canadian Pacific railroads and is in amazing condition. This was the largest bridge constructed on the new route, a double-track Pratt deck truss with concrete arch span approaches. It is much larger than the old MILW DPG bridge it replaced, which lay to the south in the flood plain. The original MILW alignment can still be made out running parallel to the new line between Polo and Lawson, and the old bridge's piers and abutments remain at the former Crooked River bridge site near Elmira.
