Most of the course will be completely closed to traffic.
However, it is ALWAYS possible for emergency vehicles, official event vehicles (e.g., referees), or police to be on the course. Therefore, even on officially closed roads, always ride cautiously. The basic rule is: ride on the right, overtake on the left.
In some areas, local residents are permitted to access the course. On these sections, traffic will be managed by the police.
Road closures will take effect 30 minutes before the start. Detailed information about the closures can also be found on the course map.
