I thought this was wonderful:
The new traffic bridge was built at the location of the river crossing in World War II, by the American soldiers from the 504th Parachute Infantry Regiment attached to the 82nd Airborne Division on 20 September 1944. This heroic crossing heralded the liberation of Nijmegen. To commemorate that event, the bridge got its name ‘The Crossing’ (De Oversteek). Two veterans were present when the bridge was opened, as well as some relatives of the 48 men who were killed in this military action. To honour these men who gave their lives for the liberation of Nijmegen, the bridge has 48 double light fixtures. These lights are lit up slowly one by one from south to north every night. A symbolic recreation of the crossing in a work of art of lights. The lighting sequence of these 48 lights is clearly visible in a time-lapse video of the opening night.
