When it’s time
Weather permitting, at 7 a.m. radio contacts will be made with people at checkpoints leading into the secured zone. If all is clear, about 7:15 a.m., the countdown will begin.
The numbers 10 through 6 will be counted out loud, the final five silently, leaving the line open in case there is an alarm.
Unless there is an alarm, the charges will be set off and the steel is to implode, dropping the steel pieces to the ground.

After the blast
A crew will determine if the charges demolished the last of the old bridge.
Another crew will inspect the new bridge to ensure there was no damage from the implosion.
The roads, trail and river could be closed until 11 a..m. Project Engineer Adam Treiber hopes to have everything reopened sooner than that.
