The fourth and final structural tower that will support Colossus, the world’s largest outdoor, center-hung 4-sided screen, was “topped off” yesterday Feb. 4, at 2 p.m. with the raising of an American flag.

In addition, the scoring pylon in the infield has been removed.

The next phase of the colossal undertaking is to install the cables that support Colossus TV as well as the state-of-the-art, 540,000-watt audio system powering 380 3-way loudspeakers and 48 stadium subwoofers – enough to make any rock star squirm with envy.

The team at Bristol Motor Speedway has put together two timelapses that give a neat view of the removal of the scoring pylon and the building of one of the four towers.

Here is a quote from Jerry Caldwell, executive vice president and general manager for Bristol Motor Speedway:

“Today marks an important moment as Colossus TV moves closer to becoming a reality. The heights and strength of these four towers give a sneak peek into the scale and true engineering marvel that will be the world’s largest outdoor center-hung 4-sided display. Construction is right on schedule as we begin the next phase of this project which involves the instillation of cables to support the display, including the video screens that make up Colossus. Anticipation is building as we prepare for our unveil of Colossus TV during the Food City 500 weekend in April.”
