In preparation for the Rhine crossing, a treadway bridge was built by the 17th Armored Engineer Battalion, detached from the 2nd Armored Division. On the night of 23 March, 1945 Company E and C constructed two preliminary treadway rafts over the Rhine, south of Wesel and opposite Spellen (now part of the town of Voerde). In the morning, a bridge that could bear mechanized transport started at 9:45 am, and by 4:00 pm the first truck crossed the floating bridge. Over 1152 feet of M2 treadway and 93 pneumatic floats were used in the project, which required just six hours and fifteen minutes to complete, setting a record for the size of the bridge. After the Rhine had been bridged, the 75th Infantry Division crossed on 24 March and the 35th Infantry Division crossed 25–26 March 1945.

American GIs of the 3rd U.S. Army forge the Rhine River. Here, some of these troops crouch low as enemy fire opens during their crossings of the Rhine in assault boats at Oberwesel, Germany. This is perhaps one of the more famous photos of the war.
