Fotografía antigua. Segunda Guerra Mundial Construcción del puente Freeman Dusseldorf. WWII photograph:Bailey Bridge over the Rhine at Dusseldorf

La destrucción que producía la guerra en las infraestructuras era atendida, posteriormente, por una fase constructora que realizaban los batallones de ingenieros para facilitar el paso de las tropas y las comunicaciones entre las ciudades.
Muchas veces los puentes construidos eran realizaciones de carácter temporal, sin embargo, esta foto nos muestra el llamado Puente Freeman en Dusseldorf que fue hecho con vista a ser  definitivo por el General del mismo nombre

Bailey Bridge Wikipedia
The Bailey bridge is a type of portable, pre-fabricated, truss bridge. It was developed by the British during World War II for military use and saw extensive use by British, Canadian and the American military engineering units.
A Bailey bridge had the advantages of requiring no special tools or heavy equipment to assemble. The wood and steel bridge elements were small and light enough to be carried in trucks and lifted into place by hand, without requiring the use of a crane. The bridges were strong enough to carry tanks. Bailey bridges continue to be extensively used in civil engineering construction projects and to provide temporary crossings for foot and vehicle traffic.

Freeman Bridge
The Oberkasseler Bridge in Dusseldorf was destroyed by retreating German forces in 1945.
The replacement Bailey bridge was designed by Major Ralph Freeman, Chief Engineer to 21 Army Group who had been involved with the early trials of the Bailey bridge. It was opened in early October 1945 and was a 2,391ft long Class 24 that used floating pontoons constructed from US Naval Lighterage pontoons and a large navigation span.
