Above Photograph (c1918) of a World War I-era camouflaged bridge in Saint-Dié-des-Vosges, France, fifty miles southeast of Nancy. Note the painted scenic panel that spans the length of the bridge (in imitation of a row of buildings) and conceals the traffic crossing it.
Below is a newspaper account of the removal of bridge camouflage at the end of WWII.

CAMOUFLAGE REMOVED FROM RIVER BRIDGE in The Valley Times (San Fernando Valley CA) July 12, 1947—
One of the last objects to be relieved of its wartime coating of camouflage is the Los Angeles River bridge on Victory Boulevard between Glendale and Griffith Park.
I.M. Ridley of Burbank today is directing two crews removing the camouflage that was placed on the bridge about six yers ago to make it appear non-existent to possible enemy bombers. Three days will be required to sandblast the paint off and return the bridge to its former white cement finish.
Most of the bombshelters have been removed from around the county’s war plants. But many buildings that produced war goods still retain camouflage.
