Loads of fireworks are being arranged in downtown Knoxville.
Pyro Shows out of LaFollete, Tennessee, are working their magic. Pyro Technicians are preparing for Knoxville's world famous firework show.
Boomsday 2012 takes over downtown Sunday.
The Henley Bridge, which usually serves as the firework platform, remains under construction. The fireworks will be shot off the adjacent railroad bridge for the second year.
"We're used to working on five lanes of the bridge normally," said Jim Edwards with Pyro Shows. "We're in a fifth of the size we're usually working in."
The fireworks are being arranged on rail cars and will be pulled to the railroad bridge this weekend.
