INDIANAPOLIS (WISH) - Preparation work for the city of Indianapolis' fireworks celebration has been underway since Sunday.
This is the state's biggest display, which is held from the top of the Regions Bank building downtown.
Show kicks off at 10 p.m. Thursday night from 37 stories in the air.
Officials say up to 300,000 people are expected to watch.
Workers have braved the heights on top of the Regions Tower since Sunday, sometimes putting in 14-15 hour days to set up.
John Maxwell, crew chief who's organized this show for the last 30 years, says the shells go up to 400 feet in the air and the low level fireworks go about 100 feet to fill in.
He said every year they try to do something different. This year, folks can expect new colors and some different effects shells.
But he also said if you come to watch, they've built some surprises in that have never been seen before in Indianapolis.
" This year the show's going to be different than in previous years," he said. "We've got a little surprise built in this one, something we've never done in Indianapolis before. We've done it in other shows, but we've never done it here, so it'll be something a little different."
The fireworks display itself will last about 18 minutes.
UPDATE 10:45 P.M.: Many Indiana State Police dispatches were reporting accidents on major roads due to slick weather conditions Sunday night.
With some of the coldest nights of the season on the way, shelters are preparing for a rush of people trying to stay warm.
Christmas is just over two weeks away, but it came early for some very special kids in Hancock County.
