Relatively few people watched the implosion from the western riverfront. From where I was on Elm St. adjacent to the Paul Brown Stadium plaza, there were no more than 5,000 people and probably fewer than that. The group I was with hurried down to the riverfront at 6:30, presuming the crowd to have already claimed the best spots. But even up until the moment of the implosion, there were still open spots along the Elm St. railing.
Those who were in place at 7:00am were treated to a spectacular sunrise (pictured above), centered perfectly above the Suspension Bridge from our angle. Packs of young kids ran around and chants rose out of the crowd at times, but the early hour and 30F cold kept things from getting rowdy.
About 10 minutes before the implosion -- the sun is behind the
Suspension Bridge's tower.
After so much anticipation, the implosion came about quite
suddenly. There was no visible or audible official time clock, until
the Paul Brown Stadium P.A. clicked on with the countdown, starting at
8 seconds. Having never witnessed an implosion, I and probably most
others anticipated a deep mortar shell sound to the charges, but it was
instead a high pitched gun shot type of sound. The charges could
be heard in perfect rhythm coming counter-clockwise from the east side
of the stadium, and as they passed along the visible west side of the stadium,
brief flashes could be seen. Nothing started falling until a second
wave of charges about 15 seconds later, at which point the stadium fell
in on itself in a counter-clockwise wave. Again, the sound was different
than I anticipated. I braced for an earth-shaking rumble, but there
wasn't any ground vibration, and there was none of the chest-thumping from
a large fireworks display. The sound of such a large structure collapsing
wasn't very loud, nor was it particularly distinct. There was no
shockwave of wind or dust.

After the implosion, a large dust cloud rose from the
site and drifted lazily north towards the downtown business district.
Within 10 minutes, it enveloped the entire front of the business district,
up to the 20th floor of office buildings. It hung around for another
10 minutes, casting an apocalyptic haze over the deserted city streets,
and Ft. Washington Way, which had been closed as well.
