The northern route was used for delivering supplies, the southern for returning trucks. Both roads were closed to civilian traffic. The highways in France are usually good, but are ordinarily not excessively wide. The needs of the rapidly advancing armies, consequently, promptly put the greatest possible demands upon them. To ease this strain, main highways leading to the front were set aside very early in the advance as "one way" roads from which all civil and local military traffic were barred. Tens of thousands of truckloads of supplies were pushed forward over these one way roads in a constant stream of traffic.
