Law enforcement officials will close part of I-35 over the weekend, or some point early next week.
Police say, they will be re-constructing an accident that happened near Troy that killed three people, including a National Guard soldier.
They say, they are trying to figure out how the soldier's vehicle launched over a concrete median, causing the six car accident.
Officers say, the road will be closed for about three hours on a night in the future.
