Traffic Impact
All impact times are approximate.
​
Traffic officials will be letting cars pass during street closures when there are gaps between runners so that there will be continuous, if delayed, vehicle access throughout the event for all businesses and residences.
​
All streets will be fully opened by 2:30pm or after the last runner has passed (whichever is sooner).
