A large force under Col. James B. Cress was organized for the reconstruction of the bridge, which included the 355th Engineer General Services Regiment commanded by Col. Thomas A. Adcock, elements of the 341st and 1317th Engineer General Services Regiments, with support from the 371st Engineer Construction Battalion, 1056th Port Construction and Repair Group, a dump truck company and an engineer maintenance company. The 371st Engineer Construction Battalion moved by a convoy code named "Boobie Trap" on March 29, 1945, from Geldern, to Menzelen, north of Alpen, Germany, preparing to move northeast towards Wesel and the Rhine River rail bridge.
The Ninth and British 2nd were pushing east at a fast pace, so the engineering companies began working 12-hour shifts of 10 days on, 2 off, on the Rhine River Bridge project. The bridge was a high-level type, approximately above high water, and of steel construction to support heavy transport trains.
The river depth, between, and current made falling into the water a dangerous proposition. Airplanes provided protection along with anti-aircraft gun emplacements and lights on the ground. The Germans were unable to pinpoint the location of the bridge construction project. On April 4, 1945, the pilings were braced and capped. The towers were completed. Steel spans, ties, and track were lowered into place.
Completion
On April 8, the Rhine River Bridge at Wesel was completed. It was tested by running a train across it that night, and the bridge passed. The following morning, 50 car supply trains began crossing the bridge, keeping to a speed limit and traveling one at a time to avoid unnecessary vibration. The Wesel Bridge was the first fixed bridge built by any army engineer to span the Rhine since the days of Caesar, according to military references, and was the first fixed bridge to span the Rhine River with highway bridges included. The "Victory Bridge" constructed by the 332nd Engineer G. S. Regiment wasn't completed until a month later, on May 8, 1945. The railroad bridge at Wesel was named the Robert A. Gouldin Bridge in honor of Major Gouldin of the 355th Engineer G.S. Regiment who lost his life during the construction of the bridge. Between April 8–10, 1945, the 3rd platoon improved the western approach to the bridge, to speed the huge volume of heavy railroad traffic using the single track approach. Other units were tasked with clearing minefields for the landing of aircraft and laying of gas pipelines. One detail was erecting a prefabricated water tower and tank for the Railroad at Büderich Station.
