In case bridges were demolished by the Germans, XXX Corps had plans to rebuild them. Plans were made to seize bridges across all these obstacles nearly simultaneously – any failure to do so could result in serious delay or even defeat. There were six major water obstacles between the XXX Corps' jumping-off point and the objective of the north bank of the Nederrijn: the Wilhelmina Canal at Son en Breugel 100 feet (30 m) wide the Zuid-Willems Canal at Veghel 80 feet (20 m) the Maas River at Grave 800 feet (240 m) the Maas-Waal Canal 200 feet (60 m) the Waal River at Nijmegen 850 feet (260 m) and the Nederrijn at Arnhem 300 feet (90 m). In early autumn this meant that observation would be seriously restricted. Dikes tended to be topped by trees or large bushes, and roads and paths were lined with trees. The ground on either side of the highway was in places too soft to support tactical vehicle movement and there were numerous dikes and drainage ditches. Highway 69 (later nicknamed "Hell's Highway") leading through the planned route was two lanes wide, partly raised above a surrounding flat terrain of polder or floodplain.
