Those supporters created quite the memorable affair as surefire Hall of Famer Peyton Manning, Super Bowl MVP Von Miller and many notable figures from the organization's past escorted the Lombardi Trophy home.
The Broncos captured the incredible scene on Twitter:

Thank you, #BroncosCountry — all 1️⃣,0️⃣0️⃣0️⃣,0️⃣0️⃣0️⃣ of you! (📸 @EnricoCMeyer) #BroncosParade https://t.co/5U70z1cRZw2016-2-9 23:31:56
Mayor Michael Hancock confirmed the number of fans to turn out for the special event:
Michael B. Hancock @MayorHancock
It's official! #BroncosParade over a million strong! Great day to be a @Broncos fan! Thank you #BroncosCountry! https://t.co/VA2bz8AHfT2016-2-9 22:50:10
As Blair Shiff of 9News pointed out, the turnout was just 650,000 back in 1998, the last time the Broncos held such an event.
For those who want to see the million in action, wideout Emmanuel Sanders—he of six catches and 83 yards to lead the team in receiving in the Super Bowl—took a video of the moment:

1️⃣,0️⃣0️⃣0️⃣,0️⃣0️⃣0️⃣ fans came out to celebrate today! THANK YOU! THANK YOU! #SB50 Champions https://t.co/nLE2VflO8Z2016-2-10 00:12:28
Running back Ronnie Hillman provided a look at the convoy as it coursed through the streets of the city:

As one could have probably guessed, the celebration wasn't limited to the players just riding around on the float and waving.
There were dabs, of course.
Dabs, as in, league MVP Cam Newton's favorite celebratory gesture. Broncos players hit on plenty of those during the festivities, which is what happens when you hold the league MVP to an 18-of-41 line with an interception and six sacks. Twitter user Harrison Berg provided one example:

Broncos fans spared no expense to make it to the event, with some going to great heights to get a look at the action, as 9News' Adam Vance captured:

Others took the opportunity to show up in creative wear to help celebrate. Joe St. George of KDVR provided his favorite attire:

The Denver Post's Jesse Aaron Paul looked at another:

"It's been 17 years since the Broncos last won," observer Jason Powers said, according to Fox 31 Denver. "I was a senior in high school so I remember coming down for that parade and had a great time. You can't miss something like this."
One recognizable face even brought along some comfort wear to make the journey through the fans easier, per NFL Network:

Folks from outside Denver helped the Broncos celebrate, of course.
One big name to do so? President Barack Obama:
President Obama @POTUS44
Just got off the phone with Coach Kubiak. Congrats to Peyton, Von Miller, and that monster @Broncos defense - see you at the White House!2016-2-9 22:30:32
The league captured the conversation between the President, linebacker DeMarcus Ware and head coach Gary Kubiak, which included quite the interesting comparison:
"That's about as good a defense as I've seen since the '85 Bears." -@BarackObama congratulates the @Broncos #SB50 https://t.co/2KNFTeuac32016-2-10 04:20:37
Manning, Kubiak and John Elway struck a pose during the course of the proceedings, as captured by the team's vice president of public relations, Patrick Smyth:

Three great Broncos quarterbacks - @johnelway, Peyton Manning and Coach Kubiak - enjoy today's Super Bowl parade. https://t.co/kv0UoOwk3d2016-2-9 23:55:55
To top it all off, Hancock and Colorado Gov. John Hickenlooper surprised onlookers at the end of the parade by announcing Feb. 9 as Bowlen Day, according to CBS Denver:
February 9th is Pat Bowlen Day!!! https://t.co/dMSyXcR5nK #BroncosParade #Broncos https://t.co/WA0z50ONVL2016-2-9 20:21:19
While it's obviously quite early, the task ahead for the Broncos looks difficult. Manning has a decision to make about his future. The allure of riding off into the sunset on top has to be strong, but so too does returning to a team that is absolutely loaded and primed for a repeat bid.
Regardless, Elway and the front office have some serious decisions to make, especially when it comes to Miller and backup quarterback Brock Osweiler, who would climb to the starter role if Manning decides to hang up his cleats.
With the celebration of an epic journey complete, the future comes into focus. For fans, though, it doesn't hurt to take the time to relive the epic celebration the next Super Bowl winner—including Denver itself—will have to match.
If Tuesday's event is any sign, the Broncos faithful have made that much easier said than done.
