Tucson will celebrate its 16th annual fireworks display from Sentinel Peak, commonly called "A" Mountain, for the Fourth of July Wednesday. The show begins at 9 p.m.

Tucson public information officer Michael Graham is encouraging residents to do a bit of research before getting behind the wheel due to the streetcar construction project in downtown Tucson and other parts of the city.

Still, he says spectators will have four good options for viewing the show.

"We're urging motorists to use 22nd Street or the frontage roads to get into the viewing locations that the city has set up," Graham says.

"Those viewing locations are TCC parking lot B off Granada south of Congress,City-State garage at Congress and Frontage Road, 22nd Street dirt lot on 22nd and Frontage Road and Mercado West end, which is the dirt lot south of Congress just west of the Santa Cruz River," Graham says.

The Tohono O'Odham Nation and Desert Diamond Casino have been instrumental in making Tucson's fireworks a reality., Graham says, contributing $30,000 while the city adds in up to $4,000.

For a few years, there was uncertainty about the event's ongoing existence due to the financial crisis and budget cuts from the city.

With the fireworks comes the risk of fires.

Barret Baker, public information officer for the Tucson Fire Department, says firefighters will be standing by in case anything goes awry.

"Statistically it actually is the busiest day when it comes to fires, and I believe about half of those are directly attributable to fireworks and that doesn't mean that you know, buildings are catching on fire," Barrett says.

"But just, you know, just between brush fires, grass fires, everything related to fires in different capacities, yeah, it is our busiest day that we see," he says.
